'reopen' may be inappropriate when a bug has been closed with a version;
all fixed versions will be cleared, and you may need to re-add them.
Bug reopened
No longer marked as fixed in versions python-escript/5.1-1.

I'm adding the "pending" tag since there seems to be a fix committed 
already, at
https://anonscm.debian.org/git/debian-science/packages/python-escript.git

Joel, if I am not mistaken and your commit fixes the build failure, please
remember to close this bug (#878496) through debian/changelog.


Regards,
Juhani Numminen
