Amey,
Looking at the end of the make output ...
/bin/sh ../../../libtool --mode=link /opt/pgi/linux86-64/5.1//bin/pgcc -O
-fpic ... -lpthread -lc -soname liblamf77mpi.so.0
-o .libs/liblamf77mpi.so.0.0.0
pgcc-Warning-Unknown switch: -soname
It appears to me the problem is that -soname needs to be preceded by "-Wl,"
so that it is passed to ld. I notice in libtool that there is a variable
'{wl}' but I don't see where it is defined. I think the definition (or lack
of) of '{wl}' is the cause of the problem.

Subject: Re: LAM: problem building shared libs with PGI
Hi,
Portland compilers require special flags to build shared libraries which
are apparently not well-supported by libtool. Please refer to the
Installation Guide (http://www.lam-mpi.org/using/docs)
where the issue is discussed in Section 4.4.4 (Portland Group Compilers)
Hope this helps,
Amey S. Dharurkar
