Thatīs a common problem also for me. I solved this using some sed
scripts. I will show you here a minimal variant which should work.

Create a small makefile with the following contents (I assume here
foo.mak):

-----foo.mak----------------------
SRCDIR:=$(shell pwd)

%.mak: %.gpr
	gpr2mak -d -r- -o - $< \
	  | sed -e 's,	$(DJDIR),	$$(DJDIR),g' \
	        -e '/^		$$(DJDIR).*\\$$/d' \
	        -e 's,^		$$(DJDIR)[^\\]*$$,,' \
	        -e 's,	$(SRCDIR),	$$(SRCDIR),g' > $@

---end of foo.mak------------------

NOTES:
 - The large spaces in the sed scripts above are Tabs !!
 - The sed scripts convert also any absolute path reference
   to you actual DJDIR directory to a refernce using the DJDIR
   variable

As you can see this is an implicit rule for generating a makefile
from a RHIDE project-file. Assuming you have a project called test,
simply run in the directory of that project (assuming foo.mak is also
there)

  make -f foo.mak test.mak


To use the generated test.mak you have to run it either with

  make -f test.mak SRCDIR=.

or modify the sed script in foo.mak.

An other alternative is to place the "%.mak: %.gpr"-rule in a global
makefile and setting the environment variable MAKEFILES to this file
so you will have this rule always available.

Are there any other problems than the above mentioned?
