Comment(by michelle.lynn.gill@…):

 A quick note that "port select python python26" MUST be run even if
 python26 is the only python installed from MacPorts AND it is set as the
 default via $PYTHONHOME in a .bashrc/.zshrc:

 {{{
  % port installed python26
 The following ports are currently installed:
   python26 @2.6.6_1+universal
   python26 @2.6.6_2+universal
   python26 @2.6.6_3+universal (active)
 % port installed py26-libxml2
 The following ports are currently installed:
   py26-libxml2 @2.6.21_0 (active)
 % which python
 /opt/local/Library/Frameworks/Python.framework/Versions/2.6/bin/python
 % echo $PYTHONHOME
 /opt/local/Library/Frameworks/Python.framework/Versions/2.6
 % sudo echo $PYTHONHOME
 /opt/local/Library/Frameworks/Python.framework/Versions/2.6
 }}}

 Despite having met all requirements except the seemingly arbitrary "python
 select," my mesa installation was failing. After running the command, it
 worked.
