am installing maildrop

COURIERAUTHCONFIG=/usr/local/courier-authlib/bin/courierauthconfig \
CPPFLAGS=-I/usr/local/courier-authlib/include \
./configure \
--enable-smallmsg=262144 \
--enable-maildirquota

make
make install-strip
make install-man

done without error, but i checked the mildrop libs

[root@linux4 maildrop-2.0.4]# ldd /usr/local/bin/maildrop
libfam.so.0 => /usr/lib64/libfam.so.0 (0x00000034b7800000)
libgdbm.so.3 => not found

/lib64/ld-linux-x86-64.so.2 (0x00000034a3e00000)

I see that libgdbm.so.3 => not found ... what could be the problem...
I have installed
wget http://mirrors.kernel.org/gnu/gdbm/gdbm-1.8.3.tar.gz
tar -zxvf gdbm-1.8.3.tar.gz
cd gdbm-1.8.3/
./configure
make
make install

without errors ....

Thanks
