compilation problems

[Dick Goldberg]

Perseverence, progress, too little know-how.

I thought swig was installed but it wasn't, so I re-downloaded and
installed it properly (I think.)
I had too recent a version and I had to go back and an older more stable
one.
Then using more good advice from these postings I got configure to work
using --with-swig=<path>.
Ran 'make' and it terminated with the message:

Entering directory ../../src/optional
No rule to make target 'all'. Stop.

Checked the Makefile in src/optional and it exists but is empty.

I have run out of ideas.  Can someone please give me a hand.
