I found the problem - when I run make in the src directory, the variables
for the ELN and bin destinations are blank, which causes the code in loadup
that is supposed to make the compilation unit names into pairs to not
bother.
Maybe these two variables should get constructed in src/Makefile.in?
Running make from the src directory shouldn't result in an unusable dump
file.
I'd probably make the code in loadup either throw an error or come up with
some reasonable default.  If you insist on having the final installation
specified, then it should just error during the build instead of producing
a dump guaranteed to fail when loaded.  Otherwise, either use some dummy
values or just treat the build directory as the install directory.
