ERROR at line 1:
ORA-00955: name is already used by an existing object
ORA-06512: at "SYS.UTL_RECOMP", line 662

Cause:

Looks like known bug#9881143 in Oracle Database - Enterprise Edition - Version 10.2.0.1 to 10.2.0.5 [Release 10.2] where an index is left from a previous failed execution of utl_recomp.

Solution: Drop the index utl_recomp_comp_idx1 left by utl_recomp and then rerun the package.
