Two problems, as tested using the output of "make dist" on zeromq2-1.git
HEAD, just now:

1) The libpgm API symbols are visible as exports of libzmq.so. Their symbol
visibility should be set to "hidden", otherwise libzmq can't coexist with
an application using libpgm externally. AFAIR, the old OpenPGM build system
did this by building all of OpenPGM with -fvisibility=hidden.

2) When doing a ./configure --with-pgm, the --with-pgm gets passed from the
toplevel configure to the OpenPGM configure. This doesn't actually break
anything but results in scary messages from configure saying "WARNING:
unrecognised option --with-pgm". This will confuse a lot of people
(including me...).
