CUPS: PKG_FAIL_REASON libusb1-1.0.9 is not available but is not asked for

[ghost]

As can be seen from below, I explicitly took libusb out of PKG_OPTIONS.cups but I still can't build because for some reason is stays in the currently selected list!

options.mk contains this:

.if !empty(PKG_OPTIONS:Mlibusb)
.include "../../devel/libusb1/buildlink3.mk"
CONFIGURE_ARGS+=        --enable-libusb
MESSAGE_SRC+=           ${PKGDIR}/MESSAGE.libusb
USE_TOOLS+=             pkg-config
.else
CONFIGURE_ARGS+=        --disable-libusb
.endif

Is there a workaround for this?

The supported build options for cups are:

        acl dbus dnssd ghostscript kerberos libusb
        pam poppler slp tcpwrappers

The currently selected options are:

        dbus dnssd kerberos libusb pam poppler slp
        tcpwrappers

You can select which build options to use by setting PKG_DEFAULT_OPTIONS
or the following variable.  Its current value is shown:

        PKG_OPTIONS.cups = dbus dnssd kerberos pam slp tcpwrappers

==========================================================================
==========================================================================
The following variables will affect the build process of this package,
cups-1.5.4nb1.  Their current value is shown below:

        * BDB185_DEFAULT = db4
        * BDB_DEFAULT = db4
        * CUPS_GROUP = lp
        * CUPS_SYSTEM_GROUPS = root
        * CUPS_USER = lp
        * JPEG_DEFAULT = jpeg
        * KRB5_DEFAULT = heimdal
        * PAM_DEFAULT = solaris-pam
        * SSLBASE (defined)
        * SSLCERTS = /etc/opt/pkg/openssl/certs
        * SSLDIR = /etc/opt/pkg/openssl
        * SSLKEYS = /etc/opt/pkg/openssl/private
        * VARBASE = /var/opt/pkg

Based on these variables, the following variables have been set:

        * BDBBASE (defined, but empty)
        * BDB_LIBS = -ldb4
        * BDB_TYPE = db4
        * JPEGBASE (defined, but empty)
        * JPEG_TYPE = jpeg
        * KRB5BASE (defined, but empty)
        * KRB5_TYPE = heimdal
        * PAMBASE (defined, but empty)
        * PAM_TYPE = solaris-pam

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/opt/pkg/bin/bmake clean' after
the changes.

Make sure to 'bmake clean' when you change PKG_OPTIONS, otherwise the value from the previous attempt could be stored in the build environment already.

Yeah, that's the first thing that came to mind, already tried before posting... didn't work.
I placed the output from bmake PKG_DEBUG_LEVEL=2 here https://gist.github.com/3987235
hope it works, first time I use gist

[updated] what I find queer is that pkgsrc says

The currently selected options are:

        dbus dnssd kerberos libusb pam poppler slp
        tcpwrappers

just before displaying correctly my PKG_OPTIONS!

[mamash]

Well, 'libusb' is the default (suggested) option for cups. Are you actually doing PKG_OPTIONS.cups=-libusb? Cause you need to do that to disable the default option.

[ghost]

argg... I thought chapter 16 was Options Handling which has no mention of this, but using search I found on p25 Selecting Build Options indicating as you did on how to disable a default option. bmake show-options is the key.

Sorry for the greenhorn bloat... it's building now.
