Remove the camunits as it couldn't find it while sitting in the
camunits/0.0.37 directory tree, the rest then installed, then typed make,
and it did. As did the make install.
Thanks, now to figure out how to use it. :)
However, the make was not very clean:

And it did NOT install convert_crop.so when I did the make install.
And since its been a decade since I actually carved new C code, I'm not
sure I am up to cleaning up this mess. convert_crop.c did not throw any
errors, but I can sure see why it can go out to lala-land & freeze. So I
think I'll print this and take it from the top with grep.
Cheers, Gene
