David,
You need to set your PATH to:
/usr/pgi/linux86-64/5.2/bin
such that when you issue the command "which pgf90" you should see:
/usr/pgi/linux86-64/5.2/bin/pgf90
I also recommend for best performance that the "-fastsse" switch be used
for compilation. This can be done when you invoke make as follows:
make LOCALFLAGS="-fastsse" serial
