[Debian-med-packaging] Fixing perl location (Was: r9759 - trunk/packages/sift/trunk/debian/patches)

[Andreas Tille]

Hi,

in a recent commit I observed several patches of the form:

While this is a perfectly possible approach to solve the problem of
fixing the Perl path it might end up redoing those patches for any new
upstream version (changed / new files etc.)  I'd regard this a boring
maintenance hell and thus I would rather try to do the following
(untestet!!!):
 

override_dh_install:
	dh_install
	egrep -rl "^#\!\s*/usr/local/bin/perl" debian | xargs -r --max-args 1 sed -i '1s%^#!\s*/usr/local/bin/perl%#!/usr/bin/perl%'


In short: If you have systematic patches to apply which do follow a
defined rule it is much more fun to implement this rule this way rather
than doing manual patches.  The same applies for adding the '-e' switch
to csh files which can be done in a similar way.

In any case you should always try to educate upstream that they could
fix this straight in their code ...

Kind regards

         Andreas.
