netsoul plugin for Gaim doesn't work with gaim2.0 (in my case, debian and ubuntu packages...).
I made a patch, after unpacking netsoul-plugin :
$ cd gaim-netsoul-0.2/src
gaim-netsoul-0.2/src$ patch -p0 < <path_to_patch_file>
gaim-netsoul-0.2/src$ cd ..
gaim-netsoul-0.2$ ./configure --prefix=/usr
gaim-netsoul-0.2$ make
gaim-netsoul-0.2$ sudo make install
That's all folks ;)
netsoul-gaim-2.0
