I would say that the "SOFTWARE_HOME" bits should be written to a
version-qualified subdirectory:

  /usr/lib/$ZOPE_VERSION

+1 for the rest of 'Chris o Christian' (making it possible to spell
the locations cleanly).  We could then even offer "omnibus-options" in
configure, e.g.:

  /tmp/Zope-2.7/configure --enable-lsb

or:

  /tmp/Zope-2.7/configure --enable-redhat

to comply with the schemes currently in use.
