A question on AIX/gcc/C++

I have a problem trying to link some C++ code on AIX 5.3:

<lj-cut text="definitely behind a cut">

I'm trying to create a shared library on AIX, containing both the source to Perl, and some C++ code. I've got the relevant parts compiling, but I'm ending up with a link failure. This is what the output looks like. I'm obviously missing some library, but I'm rather bemused as to what, since I've never played on AIX before, and have hardly ever used gcc either.

(Yes, I'm logged in as root - so sue me. I'm running as the only user, and it's a throwaway environment.)
