1.9.3-rc1 installation failed on RHEL

[airblade]

I just pulled the latest repo changes, ran sudo ./install.sh, and then rbenv install 1.9.3-rc1. Although this worked for me on my OS X laptop, it failed on my RHEL server.

The last few lines of the log are:

installing default zlib libraries

make: *** [rdoc] Error 127

And my server's details:

$ uname -a
Linux my.host.name 2.6.18-53.1.6.el5xen #1 SMP Wed Jan 23 12:33:37 EST 2008 i686 athlon i386 GNU/Linux

How can I get this working please?

Aha! Thank you.

I'm not quite sure how to pass the flag...is it $ rbenv install 1.9.3-rc1 CONFIGURE_OPTS=LDFLAGS?
