Looking at it it seems its only distributed via CVS atm.
To compile it change to the directory you fetched it into, and type:
Code:
./configure --prefix=/usr
make
make install
If indeed you did grab the archive (which is what you said) you will need to untar it. If it is a tar.gz file, use this:
Code:
tar zxf gnome-basic-tarball.tar.gz
if it's tar.bz2 then use:
Code:
tar xjf gnome-basic-tarball.tar.bz2
Obviously replace the filename with that of the actual file.
This should create a directory called gnome-basic-0.0.20 or something. cd into that dir and install it with the steps above.
