  * port:  python27 => python27 py27-xml


Comment:

 I hit this problem when updating python27, too. It looks like the problem
 comes up because something in python27's build process uses the pyexpat
 module. The python27 port provides one version, in
 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /lib-dynload/pyexpat.so, but the py27-xml port also installs its own
 version into
 /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
 /site-packages/_xmlplus/parsers/pyexpat.so. The second one has a higher
 precedence.

 If python27 is being built +universal, but py27-xml is installed non-
 universal, it will fail to load this module during destroot. The
 workaround I used was to install py27-xml +universal.
