Compiler problem with Ubuntu 8.04

[milan1612]

I installed Purebasic 4.2 following the tutorial by Bembulak.
Now when I first ran the IDE and tried to compile an example the compiler stopped
to respond and an error of the IDE showed up telling me that it couldn't restart
the compiler.
I closed the IDE and tried to compile some code via the console
and this error was printed:

milan@milan-desktop:~/Script$ pbcompiler Script.pb

******************************************
PureBasic 4.20 (Linux - x86)
******************************************

Loading external modules...
Error: Line 0 - Can't load any OSLibraries! Please re-install PureBasic

I did install all libraries that Bembulak's tutorial told me to install.
What to do now?

there is a bug in the current version, test it with sudo

This is different. The compiler cannot load the OS import libraries here.

Do you have any files in purelibraries/linux/ ?
Maybe try downloading/extracting the archive again.

Yes, these ones:

expat gdk glib glibc gobject gtk libraries pthread sdl

Funnily enough it works now
The IDE is loading the compiler again and the compilation works now
Weird...

EDIT: I restarted my computer after I got this error, maybe this was the problem?
