I don't know if I can easily explain what I'm doing.  Linux Standard
Base (LSB) requires that an application depend only on the
LSB-distributed libraries and headers.  I use the "lsbcc" compiler
(really just a front-end to GCC) to assure that I have LSB
compliance.

I compile each library via "lsbcc", then separately compile/link my
application to those new LSB-compliant libraries I just created.
The end product is a binary that is a stand-alone app except for the
LSB support which has to be in the OS already for the OS to be
LSB-compliant.  For instance, for OpenSuSE 10.0 I install the "lsb"
package, then I can install my lsb-xastir package and it runs.  This
should work across ALL Linux systems that claim to be LSB compliant.

So...  I've been statically linking each (optional) library we use
but got stumped by GDAL.  I separately have LSB-compliant versions
of libproj/shapelib/libtiff/libgeotiff (and others) linked to my app
already.  We don't depend on GDAL/OGR for those functions.  Some of
the less-used OGR map formats are what I'm still after...

If I just had some ".a" files to link to, I'd be golden.  libgdal.a
doesn't appear to have OGR functions in it, or at least the linker
gets REAL upset when I try to link to it.

FWIW I've a attached the script I use to compile GDAL under LSB to
the end of this message (It's tiny).  The important part of code for
then linking the library to my app is:

  CPPFLAGS="$CPPFLAGS -I/opt/lsb-gdal/include"
  LDFLAGS="$LDFLAGS -L/opt/lsb-gdal/lib -lgdal"
  LIBS="$LIBS -lgdal"
  AC_DEFINE(HAVE_LIBGDAL, , [Define to 1 if you have the `gdal' library (-lgdaal).])

Is there a possibility that some parts of the GDAL library compile
are ignoring the "CC" variable?

Here's the first part of the final link for my app.  The errors go
on for many pages after that:
