My final analysis on this error progression:
1. The test framework uses the in source tree copy of
system-gsymcehckrc, as it should.
2. It accomplishes this by setting the GEDADATARC environment variable,
again reasonable.
3. A side effect of this is that no other system rc files are loaded,
including system-gafrc.
4. g_rc_parse_handler (called indirectly by gsymcheck) loads user rc
files from ~/.gEDA. There does not appear to be a way to prevent this.
5. Because system-gafrc is *not* loaded during a test run, none of the
geda specific functions (like build-path) defined/loaded there are
available.
6. If a user gafrc file exists and uses geda specific functions it will
fail to load (or if it fails for any other reason), an error massage
will be output causing the test to fail, even though gsymcheck runs as
expected.
7. This will only occur during an upgrade build where the user already
has a gafrc file. It will not occur during an original install.
8. This bug only affects gsymcheck because none of the other 'make
check' runs attempt to load rc files. At least as far as I can tell.

Possible solution:
In gsymcheck/tests/runtest.sh add errors about failed rc loads, and
possibly related stack traces, to the lines removed from the output.
Ideally there should be a way to prevent non-source tree config files
from being loaded during a test run as there is no way to know what is
in them which may cause the test to fail.
