Compiling is bad?
If you compile software on your own machine it is better than download a compiled package. File conflicts? I've never had those and I've been compiling software from source since like, forever.
And again, dpkg. Another distro specific software. make is cross-distro, so it will work anywhere, as long as you have the right libs and compilers installed.
I do agree that "make install" files are harder to hunt down, but like you said, you can have the source compiled and packaged in a distro specific package and install that. I just didn't want to include it in the above "guide", because it would again be distro specific.
But if you want it, you can use src2pkg on slackware. Maybe even on some others, but I cba to try out other distros.
