You need to check which package provides the "pvm3.h"-include-file and
install that. Usually, these are *-dev(el)?-packages.

There is a pvm-dev package in Ubuntu, but it looks like Fedora employs
a different package layout, since pvm-dev seems to have /usr/include/
pvm3.h instead. See here for more details of the Ubuntu package:

http://packages.ubuntu.com/feisty/i386/pvm-dev/filelist

Had the headers been put in /usr/include, you might have been more
fortunate with the rest of the process.

I can only guess what this is doing, but I imagine that it is indeed
somewhat like the Ubuntu build-essential meta-package (which installs
some compilers and headers).

I would doubt that the default set of compilers and headers would
include PVM stuff - that's somewhat beyond what most developers would
want.

Pypvm looks like it offers the old-style Makefile generation procedure
or the new-style distutils procedure. With the old-style approach, you
could edit the Makefile and add some parameters in various places - I
guess you'd put "-Ishare/pvm3/include" on the end of the CFLAGS
variable definition, and "-Lshare/pvm3/lib" on the end of the LDFLAGS
definition. With the new-style approach, you have to persuade
distutils to pick up similar information - some packages employ
setup.cfg files for this purpose, whereas others make you specify
extra options when running setup.py.
