John,

I should have checked the glpk headers before I reported the problem, but it
would not have made any difference. The problem persists despite the
presence of the correct header files in /usr/local/include:

When I more the header files, they look OK, and the permissions look OK to
me. When I checked config.log, it had found glpk.h without problems. When I
did a find in /usr on the headers, only one copy of glpk.h and glplpx.h
appeared. I thought that we might have a freak coincidence of two headers
with the same name.

I resisted the temptation to place the missing glpk header files in
octave-2.9.8/src, where they could be more easily found. I then dug out Paul
Kienzle's old e-mail advice about building the sparse library from August 1,
and did

Joe-Koskis-Computer:/Tools/octave-2.9.8 jakoski$ export
CPATH=/usr/local/include
Joe-Koskis-Computer:/Tools/octave-2.9.8 jakoski$ export
LIBRARY_PATH=/usr/local/lib
Joe-Koskis-Computer:/Tools/octave-2.9.8 jakoski$ export LDFLAGS=-lcamd
Joe-Koskis-Computer:/Tools/octave-2.9.8 jakoski$ export LIBS="-lSystem
-lSystemStubs"
Joe-Koskis-Computer:/Tools/octave-2.9.8 jakoski$ ./configure F77=g95

and tried another make. The build again stopped at the same "was not
declared" errors, indicating that the header is still missing.

So ./configure seems to find everything, but make is having problems, even
though the headers appear to be in place with the correct permissions.

Other than the expedient fix of placing the headers where they can be found,
what else should I try?
