 you shouldn't need to specify the debug info file directly, it should
 be referenced such that GDB will find it.

 another method is to set "DBG=3D-g -O2" in mk.conf or environment when
 building (without MKDEBUG).  this leaves full debugging info in the
 normal binaries..
 
 i don't know what's wrong that it isn't working yet, but either try
 using gdb normally, or, try building with DBG as above.
