If you google around, you can see that this is a problem that happens to many 
packages on AIX, and occasionally even on Linux platforms. From what I read on 
the web, the usual suspect is that something is wrong with the xlc install, for 
example it was moved around or installed in non-standard ways, or was compiled 
for a similar but slightly different platform (for example, a different version 
of AIX, or some tools, was used on the xlc build machine).

Also from google, I see that many others do my crazy solution of linking to the 
gcc library too.

Did you try contacting customer support at IBM and asking them about this 
problem?

Have you tried setting LIBS=-lm and then configuring and building netCDF?

Thanks,

Ed
