As pointed out by Gopal, this has been fixed in the latest CVS
version of pnet.

If you have "make install"'d pnet, then it should be able to
find it without any trouble.  It is better to set CSCC_LIB_PATH
for assembly resolution than LD_LIBRARY_PATH.

It tries to emulate gcc's behaviour as much as possible.

The complicated compiler flag stuff in pnetlib, xsharp, etc,
is an artifact of how I run my system here.  I deliberately
don't use "make install", to prevent conflicts between my
work tree and /usr/local.  On a regular system, everything
is set up in the right place and "cscc" is usually sufficient.

I plan to do it one of these days when I find the time.
Or someone else can have a go if they like.  The spec isn't
100% concrete yet, so I've been holding off.

I envisage that we'll need to create some kind of "instantiate
generic" function that takes a generic class definition and a
set of actual parameters, and then builds an actual IL class on
the fly.  This can be processed with CVM in the usual manner.
