Ivan -
The only thing I can suggest is try declaring the function with the full
pathname to the "DZZUDF" library ....
ie.

DECLARE EXTERNAL FUNCTION STRLENGTH
CSTRING(32765) CHARACTER SET NONE
RETURNS INTEGER BY VALUE
ENTRY_POINT "length" MODULE_NAME "/your/full/path/DZZUDF";

where "/your/full/path/DZZUDF" is the full pathname to the DZZUDF.so
library file. (make sure the directory is executable and the file is
readable.
