building libraries

[Matthew Knepley]

I recommend reading the makefile section of the manual. Briefly, you should
at least use the bmake/common/variables makefile to get such things as
PETSC_INCLUDE correct (that is the problem here), if not use the targets in
bmake/common/rules. You could use our example makefiles as a guide.

   Thanks,

      Matt
