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=-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.
