.. unless you bind it to the executable.  Though I had never did it,
so cannot help with your problem...  Aha, it is probably just that
sh.exe was not bound with emx.exe.

Look for DOS sh in the Perl distributions. Well,

 ftp://ftp.math.ohio-state.edu/pub/users/ilya/perl/os2/5.004_55+/perl_sh.zip

is one location.

Hmm, no.  Rsx.exe is probably autoloaded by emx.exe.  Thus binding
rsx.exe directly may give you better results.

Perl comes with C file which just defines standard dl_open and
friends.  This is not a problem.  The problem is that PARI does not
know how to write "export lists".  The moment this is implemented on
AIX, it will work on OS/2 too.
