DLLD is undefined.

The real problem is that, although install() now works on OS X [ I think
and hope... ] as far as loading symbols from gp's global context goes, we
still have not tried it with external "bundles", nor built into Configure the
necessary magic to build a dynamically loadable object.

Probably something like 'ld -bundle' (?). Hopefully something generic like
'gcc -shared' would work equally well. Can you just try to Configure pari
with

  env DLLD=/usr/bin/gcc Configure

before reconfiguring gp2c ? [ actually, does 'make bench' succeed in building
gp-dyn after this change ? ]

If it does work, then a trivial fix to config/get_dlld might do [ just have
to add darwin to the list of supported systems, lines 12-24 ]

P.S: all this rather belongs to pari-dev [ none of the above apply to the
stable version ]. Let's move the discussion there.
