FYI, I just filed this bug.
The rbconfig.rb file shipped with Nevada build 79 contains bogus paths that
prevent gems that require use of a C compiler from working. e.g.,
ruby-postgres. On SPARC, the file
/usr/ruby/1.8/lib/ruby/1.8/sparc-solaris2.11/rbconfig.rb, refers to the
following paths which we shouldn't expect to exist on a user's system (even
inside Sun.) The x86 version has the same problems.
* /opt/onbld/bin/sparc/install -c
* /opt/SUNWspro.40/SS11/bin/cc
* /gates/sfwnv/builds/sfwnv-gate/proto/...
These should be removed.
Having the -L/gates/... here prevents gem generated Makefiles from compiling
anything.
After removing these paths from rbconfig.rb, I ran into another problem: the
ruby-postgres gem build configuration adds the gcc compiler option -Wall which
is illegal for Sun Studio. This is a bug with the ruby-postgres extconf.rb file
and the following changes fixed it:
$ pwd
/var/ruby/1.8/gem_home/gems/ruby-postgres-0.7.1.2006.04.06
$ diff -c extconf.orig.rb extconf.rb
