[MPlayer-users] Error: The GUI requires GTK devel packages (which were not found)

[Albretch Mueller]

 Actually after installing libgtk2.0-dev:
~
 http://packages.debian.org/squeeze/libgtk2.0-dev
~
 I then got:
~
 undefined reference to `th_brk'
~
 Any idea of why this error is happening and how to troubleshoot it?
~
 thanks
