 I am a Mozilla developer, we recommend that our Mac OS X developers use
 MacPorts to get build dependencies (like Mercurial, libidl, autoconf213).
 Mozilla's build system will use python2.7 from MacPorts over the system
 python if it exists, which it does in my case because it was a dep for
 something else I installed via MacPorts. I get the following error when
 trying to build Firefox with a deployment target of
 MACOSX_DEPLOYMENT_TARGET=10.5:

 {{{

 }}}

 I assume this is because MACOSX_DEPLOYMENT_TARGET is set to 10.5 for the
 Firefox build but it was set to 10.6 for the python2.7 build. For some
 reason the current state of MACOSX_DEPLOYMENT_TARGET matters for python2.7
 when it shouldn't.

 If I force the Firefox build to use python26 from MacPorts
 (PYTHON=/opt/local/bin/python2.6) this problem doesn't happen so I think
 this problem is specific to python27 from MacPorts.
