cannot compile transcode

[laurent.perron@…]

sudo port install transcode +a52dev +x264 +xvid

lead to the following error:

I am running leopard using xcode 3.0

I don't know how to go about fixing the port, but I was able to get the file in question to compile by adding "-lmpeg2convert" to the end of the compiler flags. Presumably a small change to the Makefile will solve it.

libmpeg2convert's ld flags get picked up by pkg-config and libmpeg2convert is required to build. This port doesn't depend on pkgconfig and if configure picks up a non-ports pkg-config, that one won't know about the ports configs directory, so it never gets added to LIBMPEG2_EXTRA_FLAGS and thus never included in LIBMPEG2_FLAGS. This patch fixes the problem on a Mini/PPC, 10.4.11:

I suspect it wouldn't be OS or architecture dependent.

A dependency on pkgconfig was added in r39706. Thanks.
