Thanks for the reply. I've found and installed the package containing pvm3.h. (The file is now located under "share/pvm3/include/pvm3.h".) But Pypvm can't find it.
Someone recommended that I install the equivalent of what is called "build-essential" in Ubuntu. I was told that the equivalent can be achieved in Fedora like this: sudo yum groupinstall "Development Tools" --exclude=systemtap -- exclude=systemtap-runtime I don't quite understand what these packages are supposed to do, but they don't seem to help. Can anyone tell me how to make (the installation program for) Pypvm understand where the header file is? Thanks in advance. -- http://mail.python.org/mailman/listinfo/python-list
