[Python-apps-team] Bug#491109: mercurial: Unreliable test for "wish" in postinst.

[Daniel Kobras]

Package: mercurial
Version: 1.0.1-3
Severity: normal

Hi!

When mercurial's postinst checks whether to enable extension hgk, it
runs

	which wish > /dev/null || enable=false

but wish is handled via alternatives, and might only become available
later on if mercurial and tk8.4 are upgraded in one batch. Lacking
something like a "Pre-Suggests" to avoid this situation, maybe the test
could be expanded to eg.

	which wish > /dev/null || test -d /usr/share/doc/tk8.4 || enable=false

or even a version that's less kludgy.

Regards,

Daniel.
