1) "compat32-libraries"
64bit edition of Porteus has support for executing of 32bit applications built into kernel.
However, applications which are not compiled statically still needs 32bit shared libraries to run.
Please download and activate compat32-libraries module if you want to run 32bit applications
(wine, teamviewer, adobe reader, etc).

2) "compatKDE4-libraries"
This is a collection of libraries needed to run some Porteus modules
under KDE4 desktop. These libraries are gathered from Slackware
packages and not present in Porteus ISO by default due to the size
and/or functionality concerns (libnepomuk as an example).

3) "wine"
wine is 32bit and requires "compat32-libraries" to run.
