compiler questions on rs/6000

[Stuart McNicholas]

Dear Professor Alexander,
  This I agree is slightly worrying. We have an SP here in Birmingham on
which we are successfully running molpro2000. Each node is running AIX
4.3.3 and the program was compiled with xlf 6.1. This seems similar to
your setup, even though the underlying machinery might be slightly
different. The program also ran on AIX 4.3.2, and has been known to work
on much older versions of AIX. 

One thought - are you using a system blas library? It could be that you
are using the wrong one, since AIX installs various ones for different
architectures. For instance there is a choice of -lessl (correct for our
machine) or -lesslp2 (incorrect for our machine) on our system. You
could try building the program with molpro's own built in blas routines.
If the blas library is not the problem, then I will have to think again. 

Regards,
Stuart McNIcholas
