[Ltib] a bug of ltib - build gdbm while gdb is wanted.

[chen gang]

Is this a bug of ltib? 
I can bypass this by disable gdbm from pkg_map.






address@hidden non-distributable-ltib-modelo-20100708]$ ./ltib --m prep --pkg gdb

Processing: gdbm
==================
Build path taken because: directory build, build key set, no prebuilt rpm, 

Cowardly refusing to clobber existing directory:
 /home/user1/linux/non-distributable-ltib-modelo-20100708/rpm/BUILD/gdbm-1.8.3
Remove this by hand if you really want to rebuild this package from scratch



f_prep() returned an error, exiting
