I don't normally have any problem installing tarballs; but, I am being
cautious about doing it in Gentoo.

I assume that it will install fine, but I don't want to end up installing
things without a good method of file tracking, so I can remove it cleanly
if/when the time comes.

How do the experienced people here go about installing/tracking their
tarball installs?

TIA...
