Summary:                    Missing rb_hash_foreach
Description: 
Configure scripts check if rb_hash_foreach function exists
using the following command.  if it does not exist, it is assumed the
release level is prior to 1.8.2.  

$ /opt/csw/bin/ruby --version
ruby 1.8.7 (2008-08-11 patchlevel 72) [sparc-solaris2.8]

$ /opt/csw/bin/ruby -r mkmf -e 'have_func("rb_hash_foreach")'
checking for rb_hash_foreach()... no

---------------------------------------------------------------------- 
The have_func feature of mkmf is a header test.  The function is defined in
/opt/csw/lib/ruby/1.8/$arch-solaris2.8/intern.h.  I'll determine why the
test is failing to find this function.

Confirmed on solaris 10 x86 (other platforms not tested yet).

have_func builds a small c extension that requires the rb_hash_foreach
symbol.  This is linked against ruby-static.  The ruby-static library isn't
included with the package.  I'll resolve this asap.

---------------------------------------------------------------------- 
Modified the GAR build to allow libruby-static.a to be bundled.  Have
verified the problem is resolved after including this file.  I'll have
packages in testing/ by days end.

I have tested it and ruby itself works fine.

however, the dependency list is wrong or there is still a bug  ;)

I found that I actually needed the gcc binary itself and not just the
libraries
for mkmf...have_func  work correctly

The output of mkmf.log is below. 
without gcc it rb_hash_foreach returns no and fails with the shell command
{path to gcc}/gcc not found.  

$ cat mkmf.log 
have_func: checking for rb_hash_foreach()... -------------------- yes
