Unmarked dependency on python 2.5 in devel/glib2?

["Ian D. Leroux" <idleroux%fastmail.fm@localhost>]

With pkgsrc updated a few minutes, make package in devel/glib2 fails
with:

...
gmake[5]: Entering 
directory`/pkg_comp/obj/pkgsrc/devel/glib2/default/glib-2.30.2' 
/bin/sh ./config.status --recheck
gmake[5]: Leaving directory 
`/pkg_comp/obj/pkgsrc/devel/glib2/default/glib-2.30.2'
  GEN gdbus-test-codegen-generated.c
env: python2.5: No such file or directory
gmake[4]: *** [gdbus-test-codegen-generated.c] Error 127
...

I'm building this in a pkg_comp chroot, which is why python isn't
available until and unless it gets installed as a dependency.  Should
python be added to glib2's dependency list, or is something else going
on?
