PS. you don't need to set GNUSTEP_MAKEFILES, it's set automatically by
GNUstep.sh.

One trick which can be helpful is to make sure that the tools are
compiling and linking against the non-installed versions of the libraries.

It seems your problem is that the tools are built against the installed
versions of the libraries (then, of course, you need to install the new
libraries first before being able to use them).

In the GNUmakefile for the tools, you can add something like - 

ADDITIONAL_INCLUDE_DIRS += -I../Source
ADDITIONAL_LIB_DIRS += -L../Source/obj

with the appropriate -I and -L flags (those are just examples for a single
library in Source, with headers in Source too.) to make sure that the
tools are using the libraries and library headers in the package itself --
not the installed ones.

To make sure this is satisfied, you can delete the installed libraries,
and try compiling everything (with a single 'make' at top-level), then
hack the -I and -L flags until it compiles by finding headers and
libraries in the non-installed locations.  :-)

If you're confused, you can also have a look at gnustep-base or
gnustep-gui for example which are doing this.

Apologizes if I missed your question/problem, and you already knew this.
