That was a good thing to do. Since you don't have a clue about compiling
software from source and repeatedly managed to break your installation,
you better stick with the pre-compiled binaries. GIMP 2.6 will come to
your distribution soon enough.

 ./configure --help

 You will notice that there's a --disable-docs option. Have you
 tried to use that?

OK I did that and after updating a bunch of libraries Gimp 2.5.2 
compiles and starts.  But when I open the default document it shows 
up black. When from the Color menu I select invert the program 
crashes. 

I recognize that it is a development version. Still this is a bit 
discouraging.

AFAIK GIMP does not have a 'default document'. What do you mean.

When from the Color menu I select invert the program
 crashes.

Try unchecking the 'Use Gegl' checkbox in the toolbox and then using
invert. If it works OK,  there may be something wrong with your BABL
or GEGL installation.


 I recognize that it is a development version. Still this is a bit
 discouraging.

It may also be a bug in BABL or GEGL only triggered by a particular
quirk of your system.

HTH,
David

 There have been segfaults when GEGL was used to process the demo

Well I have deinstalled 2.5.2 and gone back to 2.4.5. I hope the value 
added by the gegl package is worth the extra install effort and the 
greater risk for failure.  What pressing need does it address?

On every one of the 5 installations I've done, it's been easy to do
and worked fine immediately. You simply lucked out. That said, GEGL
isn't production standard yet -- mainly because it needs more testing
(which GIMP will provide by using it). So, your efforts to get it
working on your system are appreciated.

GEGL is a huge step for GIMP towards doing image processing in the
'right way' -- ie. flexible, avoiding unnecessary destruction of
useful data, and easy to extend. One of the concrete benefits of GEGL
is, it allows GIMP to replace special casing for RGB, Gray, Indexed
image types with code that can simply work without special casing --
less code == less bugs.

Another is that it reduces the size of the GIMP core codebase (which
is sorely needed, esp. for attracting new developers) by allowing any
special-case optimizations that are wanted to be done outside GIMP and
plugged into GEGL. (it is currently a bit slow, so there will need to
be optimizations)

I hope you will try again, perhaps when 2.6 is released.
