Ouch.

Great!

Ack, quite common behaviour.

There is prior art for the first option (assert_lib()):

% grep assert_lib ../*/debian/patches/*
../libauthen-krb5-simple-perl/debian/patches/fix-checklib-fail.patch:+assert_lib(
../libcrypt-dh-gmp-perl/debian/patches/fix-checklib-fail.patch:+    Devel::CheckLib::assert_lib(@dcl_args);
../libdata-structure-util-perl/debian/patches/fix-checklib-fail.patch:+assert_lib();
../libipc-sharelite-perl/debian/patches/fix-checklib-fail.patch:+assert_lib();
../libmath-tamuanova-perl/debian/patches/fix-checklib-fail.patch:+assert_lib(
../libopengl-xscreensaver-perl/debian/patches/fix-checklib-fail.patch:+assert_lib(lib => ['X11', 'GL']);

Hm, something generic would be nice but I'm also a bit afraid of side
effects.
