Should be linked libgnuradio-blocks, right?

Hi Carlos,

you seem to be setting up linking correctly (if you're not even
requiring more GNU Radio modules than actually necessary in your main
CMakeLists.txt); however try doing
ldd /usr/local/lib/libgnuradio-MLABlocks.so
and check whether the library really is linked against libgnuradio-blocks.

Greetings,
Marcus
