I see at least 2 packages from your list in repository:
http://repository.maemo.org/extras-devel/pool/chinook/free/libm/libmad/
http://repository.maemo.org/extras-devel/pool/chinook/free/f/flac/

You should probably agree about this with mplayer maintainer. If I
remember correctly flac and libmad are mplayer dependencies. Most
probably I built them sometimes ago for mplayer. I'm helping Sergey with
packaging.

I'd suggest to take packages from Debian:
http://packages.debian.org/lenny/scummvm
and tweak them a bit.

I'd go this way:
wget
http://ftp.de.debian.org/debian/pool/main/s/scummvm/scummvm_0.11.1-1.dsc
http://ftp.de.debian.org/debian/pool/main/s/scummvm/scummvm_0.11.1.orig.tar.gz http://ftp.de.debian.org/debian/pool/main/s/scummvm/scummvm_0.11.1-1.diff.gz && dpkg-source -x scummvm_0.11.1-1.dsc && cd scummvm-0.11.1/
After making changes you should run dpkg-buildpackage -S 

You can find a lot of info about Debian packaging here:

I can help you, but you should try yourself first and ask questions :)
