test won't work

Hi

I finally finished to compile everything and the dev version is working 
very well indeed thanks to the LC_ALL=C make.

One of the version I compiled was the one w/o gui (autogen 
--disable--gui). I ran a "make check" and it seems there are some not 
configured tests. Is it normal? Do I have to investigate more?
