I created a new libIDL pacman package, but I am not happy with the way this is handled: too much unwanted work editing that PKG file and having to figure it out, I would like more automation. I would suggest the way "checkinstall" for Slackware does it: You should just run "makepkg" in the working directory and that would "emulate" a configure/make and a
make-install installtion and record where files go where (also inline ask for specific configure attributes on the shell). And then it creates the package with all the files in the right place and asking the packager for
info if needed in an inline editor. Regarding dependancies you could run ldd to check out the extra libs needed for this specific package and then compare those to the skeleton -base version of Arch.
