Links against private Mono.Cairo lib; prevents apps from running

[Jo Shields]

Binary package hint: gtk-sharp2

As part of the Mono 2.0 transition, GTK# had a dependency on libmono-cairo1.0-cil changed to libmono-cairo2.0-cil. Unfortunately, a pkg-config file for Mono.Cairo is only included in the former. As a result, the 2.12.7-1ubuntu1 package on Jaunty attempted to compile its own local private copy of Mono.Cairo, and links against it. This package is signed with a version key which differs from the system version - and as the private lib is not installed, all apps are unable to find the "missing" lib.

The attached 1ubuntu2 patch fixes this issue by forcing configure to build against the system version of Mono.Cairo 2.0 (in the absence of valid pkg-config data).

Sponsored, thanks!

 gtk-sharp2 (2.12.7-1ubuntu2) jaunty; urgency=low

   * debian/rules:
     + Set MONO_CAIRO_LIBS=-r:Mono.Cairo to manually provide Mono.Cairo
       build information (instead of using the 1.0-only pkg-config entry)
     + Set MONO_CAIRO_CFLAGS to " " to fool configure into not asking
       pkg-config for mono-cairo.pc

Seems to fix all issues for me, thanks for reacting to this so quickly!
