I see this recent post on the same subject:
http://lists.gnu.org/archive/html/libtool/2010-11/msg00035.html

PGI offers this work-around:
http://www.pgroup.com/userforum/viewtopic.php?p=8419&sid=2b25bde02111e5b26f00709197c2a5eb
Which means you create a ~/siterc file with the contents:
switch -pthread is replace(-lpthread) positional(linker);

I've verified that the work-around works, but it would be nice to get this fixed in libtool.

What's the bugfix status on translating -pthread to -lpthread for PGI compilers?
