autopano-complete cannot find Mono executables

Binary package hint: autopano-sift

Package: autopano-sift
Version: 2.4-0ubuntu4
Severity: normal

/usr/bin/autopano-complete looks for generatekeys.exe on $PATH, but in this package it resides in /usr/lib/autopano-sift/. autopano-complete thus fails with an obscure error message ("dirname: missing operand").

The why: I've manually installed Hugin 0.7-beta4 (and its dependencies) in /usr/local on a Dapper machine, but since the latest autopano-sift was already packaged I thought I'd use it. This version of Hugin uses autopano-complete, which fails as described above (it expects it to be called "autopano-complete.sh", but that's easy to deal with). Putting /usr/lib/autopano-sift on $PATH is a successful bodge.

There is a commented-out bit at the start of autopano-complete to use a hardcoded path instead of "which", which looks like the Right Thing here.

(While this bug is reported against the Dapper version, 2.4-0ubuntu4, I've also verified that it applies to the latest, 0ubuntu5.)
