hallo john, either you have not installed liblrdf or liblrdf-dev, that 
will the most probably.

to have the


working properly in debian, i put this line into my .bash_profile:


(note:this both lines  in original are only one line!)

...so the point is to find out, where on your system the libraries have 
installed their .pc files.

try first running 'updatedb' as root, and than:

locate pkgconfig

once you find out the path(s) you can modify the line to catch the ones 
in your system.

since 64studio is a debian derivate, it should work the same way...

for changes to apply, you have to logout and login again the user.
