If the libcr is not installed under standard locations, on the prompt you
can do
$> locate libcr.so.0
to find the location and set your LD_LIBRARY_PATH to point to this dir.
Also you may want to configure LAM with --with-blcr=/blcr/path/dir if BLCR
is not in standard location and you want CR support in LAM.
