(string-delete #\. version)
Also, please add a 'file-name' field so that the source filename in the
store will be called *-libsvm-3.20.tar.gz instead of *-v320.tar.gz.

I tried building this, I noticed that the installed binaries (svm-train,
svm-predict, and scm-scale) don't reference libsvm.so.2. In the build
output, I see no header files and no libsvm.so symlink, so I don't see
how this library could be used.
Thanks,
