Looks like Ruby is picking up some more system libraries. I wonder
if it's possible to plug-in a check into the RPM build phase to
look for references to external libs. On Linux / Tru64 it's possible to
view the shared libs dependencies.. Solaris probably has this too.
Might be useful to only allow certain system libs and fail in case
a non-approved system lib is linked to. 


ie. on Tru64 looking at /openpkg/lib/ruby/1.8/alphaev68-osf5.1b

   ^^^ linkage to iconv, OpenPKG also has a libiconv

       line in the spec
