have to compile that in (gdb) ... using --enable-debug configure option, 
and as the other jim noted you should provide some kind of command line 
parameter ... try povray -version at the bare minimum just to test that 
your build worked proper. here's a an article that can help get you 
going with gdb:

http://www.ibm.com/developerworks/library/l-gdb/

to summarize first do:

gdb povray

then when you get the (gdb) prompt do:

run ~somepathname/to-a/scene-or-ini-file/test.pov

it should be in a directory that you have write capability
