I tried this last night with Ubuntu (Warty). The openssl package doesn't include header files so presumably you would need to install openssl-dev, only that package doesn't seem to exist in Ubuntu-land. I gave up at this point and installed on a different system.

The README file for cogito/git mentions that there is an ssl library included in the source which you can use if you don't have openssl. It doesn't give any directions on how to use it, however. You could try looking into using that.

Use

	make MOZILLA_SHA1=1

to use the included mozilla-based SHA1 library.

(Or just do "export MOZILLA_SHA1=1" in your .bashrc so that you always do this).

There's also a "PPC_SHA1" which works the same way, and which enables the optimized ppc assembly language version. It used to make a big difference for me, but it seems modern openssl libraries already have something fairly optimized (on my YDL machine the openssl version was really slow).
