odd macport config

[Floris van Manen]

I've got OSX Lion running
I've used MacPort to install python27
When i want to install Lilypond with MacPort, it asks for an odd combination: 
python26 and py27-libxml2
Is there a particular reason for lilypond to insist on using python26 instead 
of the already installed python27 ?

Thanks!
Floris
