Please show
  /bin/sh ../libtool --version

and if that is not 1.5.20, please update the package to use 1.5.20.
We've fixed bugs in the PGI handling code.  Also please note the exact
PGI version -- they've fixed some bugs in the v6.0-5 version I believe.

If both is current, then please rerun the link command with --debug, and
send the output, preferably packed (bzip2, gzip), along with
'../libtool --config' output.

By the way:

I'm sorry.  Next time just write a mail after a couple of hours.  ;-)

Cheers,
Ralf
