Rene, You're not going to believe this... The good news is that someone at our university is paying for Compaq support and they let me use their authorization number to phone the experts. Here's the story: When you install CXX version 6.2 it puts the new libraries in /usr/lib/cmplrs/cxx. It does NOT update the copy of libcxx.so in /usr/shlib. Adding "-L/usr/lib/cmplrs/cxx -lcxx" to the f90 link command makes it compile much better. The official reason for this, according to the guy at Compaq: "It doesn't update it because, basically, it doesn't have to." Tech support did not fully recomend overwriting the old version since the new version may cause some other troubles on our slightly dated OS. When we install version 4.0F I'll clean that up.
