Bug#309152: tipa: upgrade problems related to tetex-bin

[Frank Lichtenheld <djpig@debian.org>]

Package: tipa,tetex-bin
Severity: serious

If tipa and tetex-bin from woody are installed and I upgrade to
sarge the upgrade fails, if the new tetex-bin is configured after
the new tipa:

Setting up tipa (1.2-1) ...
texhash: Updating /usr/local/share/texmf/ls-R...
texhash: Updating /usr/local/lib/texmf/ls-R...
texhash: Updating /var/lib/texmf/ls-R-TEXMFMAIN...
texhash: Updating /var/spool/texmf/ls-R...
texhash: Done.
updmap: config file updmap.cfg not found.
dpkg: error processing tipa (--configure):
 subprocess post-installation script returned error exit status 1

This is probably because /usr/bin/updmap already exists but
updmap.cfg not yet.

There are usually several solutions to this:
1) tipa could check both for the executable and the config file before
   calling updmap
2) updmap could fail gracefully if tetex-bin isn't configured yet.
3) tipa could depend on tetex-bin
