Edgewall TRAC update from 0.12.3 to 0.12.5 (Debian 7.2 - Wheezy) - DistributionNotFound

When I update TRAC of 0.12.3 to 0.12.5 using "aptitude" (Debian 7.2), the file "/usr/local/bin/trac-admin" was not updated automatically, generating the following error:
root@SERVER:/home/users# trac-admin /home/trac/PROJECT
Traceback (most recent call last):
  File "/usr/local/bin/trac-admin", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2711, in <module>
    parse_requirements(__requires__), Environment()
  File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 584, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: Trac==0.12.3
To solve the defect, it was necessary to change the following items of the file "/usr/local/bin/trac-admin":
#!/usr/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'Trac==0.12.3','console_scripts','trac-admin'
__requires__ = 'Trac==0.12.5' #Changed from 0.12.3 to 0.12.5
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('Trac==0.12.5', 'console_scripts', 'trac-admin')() #Changed from 0.12.3 to 0.12.5
    )

That's all!
