There have been fixes for the Portland compilers added in CVS Autoconf.
Please try it together with the patch below.  If that does not work,
please post the part of config.log that starts with something like
| checking how to get verbose linking output from pgf95

and ends after(!) the result of the test
| checking for Fortran libraries of pgf95

Please don't post the whole config.log, please do not munge the contents
in any way (i.e., copy and paste, if your mailer does not wrap long
lines, else attach, don't just post an "interpreted" version ).  Please
keep in mind that you should always post the exact findings, in addition
to any interpretations.  If you would like to suggest a change to
Autoconf, it's best to post a unified diff, as shown below.  Such can be
created with 
  diff -u lib/autoconf/fortran.m4.orig lib/autoconf/fortran.m4

for example, or with `cvs diff -u'.

Note that most likely it will need further changes to Automake/Libtool
to make inter-procedural optimization work in nontrivial cases.

Cheers,
Ralf
