277	mbuild gets null_pointer_exception when segments with unknown suffixes are encountered	Eric Swenson	Gary Dixon	"I tried to use mbuild to build bound_sipb_maint_, which includes in the source, a .gdt segment. Mbuild doesn't know how to process these, but it shouldn't get a null_pointer_exception when it encounters this.

It also is too verbose when it can't find the library for a new source.  See the output below:
