why you installing frmo source?
abiword is in the slackware install disks as slackware package. (.tgz)
read UPGRADE.txt on CD1 for instructions on mass-installing.
basically upgradepkg --install-new */*.tgz
(tho some caveats attached especially if upgrading)
and erm, what are you using to extract? shouldn't extract to the "desktop". (what desktop, kde, gnome, whatever?)
I'd recommend tar -xvzf filename.tar.gz in future for undoing tarballs, but stick to packages wherever possible anyway. www.linuxpackages.net
for stuff not in the main install.
