No, I don't think that you did anything wrong.  There are just other  
bugs wrt to PGI in our configure logic that I haven't spotted yet.

This would all go a lot easier if I had a modern PGI compiler  
available for testing.  In the mean time, I would recommend just  
editing the generated mpichconf.h after the configure step and before  
the make step to define HAVE_GCC_AND_X86_64_ASM to 1.  That ought to  
fix your immediate problem, although there may be others that will  
appear once you are over this hurdle.

I'm not sure that there's much more I can do for you in the short-term  
until I get my hands on a PGI compiler installation.  In the medium- 
term I'll see if I can get this resolved for the 1.1.0 stable release  
(likely some time in May).

Sorry,
