Arch Linux

I decided to modify the UPX PKGBUILD http://aur.archlinux.org/packages.php?ID=1625 to have LZMA support.

What I discovered is we have a package called "lzma" http://aur.archlinux.org/packages.php?ID=5818 located at: http://tukaani.org/lzma/

In Gentoo, this is called "lzma-utils" http://packages.gentoo.org/package/app-arch/lzma-utils which makes far more sense and won't get confused with the lzma-sdk.

A lot of distributors are calling it "lzma" which is bad because there's another project http://packages.gentoo.org/package/app-arch/lzma which is the lzma-sdk from http://www.7-zip.org/sdk.html (We don't currently have a lzma-sdk package I was going to create one).

It was only in the UPX readme when it said this, export UPX_LZMADIR=$HOME/local/src/lzma-4.43 and there is no 4.43 version of our "lzma" package I discovered that they are actually talking about the SDK, and as it happens the gentoo UPX package is also depending on that very same "lzma-sdk" except for the fact they call it just lzma.

To make matters worse there is a lzma-4.999.3alpha.tar.gz and lzma-4.42.2alpha.tar.gz alpha @ http://tukaani.org/lzma but I found it highly unlikely UPX would be depending on those, as UPX hasn't had an update in quite some time.

I'm proposing that we rename "lzma" to "lzma-utils" and have a "lzma-sdk" package.
