r.mapcalc is quite important; post the errors you are getting to the 
developers' mailing list if  you need help getting it working.

It should come with GDAL when you install it. Have you installed GDAL 
properly?

You don't need GRASS support in GDAL. That is only if you want GDAL to be 
able to read GRASS databases for some third party application. Anyway the 
problem you have is that libgrass does not come with GRASS and is 
separate. But you don't need it. Just don't use --with-grass

Ah I see you are using the new direct GRASS support in GDAL, not libgrass. 
But you need GRASS 5.7 for that. But again, you don't need GRASS support 
in GDAL to use GDAL with GRASS. GRASS can read it's own format. You need 
GDAL to read other formats.

You don't need to compile or install 5.3 to use 5.7. You just need the 
source code. The 5.7 CVS doesn't contain the source code for those modules 
that haven't changed between 5.3 and 5.7.

No that should be no problem.

You only need motif for xganim and blas and lapack for s.surf.krig which 
is not compiled by default (i.e. you don't need them).

Hope this points you in the right direction
