Build Identifier:

The ruby driver wants to always install itself into the system-wide ruby directory, which requires root. This should not be the case, if a prefix is given, that should be used/

Reproducible: Always

The default location for ruby gems on Darwin is /Library/Ruby/Site/2.0.0. We get this path by asking ruby itself:
ruby -rrbconfig -e "puts RbConfig::CONFIG['sitelibdir']"
The question is, what should we use in stead?

What we do now is try to match ruby's installation prefix with the sitelibdir value, and if the former is a prefix of the latter, we subtract that prefix from sitelibdir and use the remainder and stick it on to our own prefix. On Darwin, there is no match (the prefix as returned by ruby is /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr), so we don't do that. What we could do is just glue the sitelibdir that is returned on to our prefix. You would then get
/usr/local/Library/Ruby/Site/2.0.0 (assuming --prefix=/usr/local).

Is that acceptable?

I think that would be acceptable!

Changeset dec9f780e76d made by Sjoerd Mullender sjoerd@acm.org in the MonetDB repo, refers to this bug.

Changeset description:

When Ruby's sitelibdir is not inside its own or our prefix, append it.
This has an effect on Darwin where Ruby's prefix is
"/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr" but its
sitelibdir is "/Library/Ruby/Site/2.0.0".  So we install our gems in
"$prefix/Library/Ruby/Site/2.0.0" now instead of in
"/Library/Ruby/Site/2.0.0".
This fixes bug #3678.
