[Help-gnunet] missing lib in GNUnet-0.5.4 ?

[Adrien]

Hello,

I  recently tried to install GNUnet. 
The installation procedure was:
./configure
make
make install (as root)
mkdir ~/.gnunet
 cp contrib/gnunet.conf ~/.gnunet/

... as seen ine the README file


But, I cannot run gnunetd:

$ gnunetd -d
May 18 21:35:18 Could not open library libgnunetafs_database_gdbm (file not 
found)!
May 18 21:35:18 __BREAK__ at logging.c:226
$

There is nothing called  "libgnunetafs_database_gdbm"  in any lib/ directory.

I got the same problem with 0.5.3

I'm using Debian unstable

Can someone tell me where did I go wrong ? 
Thank you
Adrien
