heh, the usual answer to a question like this comes from a google search for the library and maemo

"librdf maemo"

in this case however, you have entered a loop:
http://www.google.co.uk/search?q=librdf+maemo

result 1 is your own question

it will have to be built specifically for maemo, and whilst some things can just be "./configure; make; make install"ed *, some things require more work.

* with high amounts of foo :P it would usually require packaging as well
