Your attachment had:

file: No such file or directory at
/usr/lib/perl5/5.8.8/x86_64-linux-thread-multi/DynaLoader.pm line 230.

So it cannot find librdf.so - the shared library - so it must not be
in the standard library search paths.

The compile line above hints you installed redland into /usr/local
(the default configure, or configure --prefix=/usr/local)
then the librdf.so would have gone into /usr/local/lib.

On most systems the default shared library search path is usually
/usr/lib and /lib so you cannot dynamically link against
libraries in /usr/local/lib by default.

To fix see man ld, man ld.so, either edit /etc/ld.so.conf or
install redland under /usr/lib OR
export LD_LIBARY_PATH=/usr/local/lib
depending on your system.
