webkit-gtk2-1.2.7 doesn't upgrade after changing python to 2.7

[Gritsuk Anton]

HI!

Now i'm using FreeBSD 8.2 (r219048):
  # uname -srm
  FreeBSD 8.2-STABLE i386

I upgraded and replaced my Python 2.6 to 2.7 and all packages is related 
of this. I use instruction from /usr/ports/UPDATING:
   # portupgrade -o lang/python27 lang/python26
   # cd /usr/ports/lang/python && make upgrade-site-packages

After this  update, installation/upgading of webkit-gtk2 is failed.

Let's see:

  # portupgrade webkit-gtk2-1.2.7

If I replace first string in /usr/local/bin/g-ir-scanner:
  #!/usr/local/bin/python2.6 to #!/usr/local/bin/python2.7

my upgrade finish successful.

Please, investigate this problem.
