Suse 11.3 OSS : # zypper in glib2-devel
rpm -ql glib2-devel | grep libgthread : No libgthread-2.0.la in Suse.
Get the file from this package ( It's a very small text file.)

But there is really no reason to compile vlc :

> Installing VLC using 1-click-installs > on 11.3 >> vlc.ymp
Click the downloaded file 'vlc.ymp'.
Then Yast will install vlc and its dependencies.
