This part will be the most painful one to debug.  First of all, what
perl --version?

Then, could you *replace* lib/Autom4te/General.pm with the following
one, and rerun the same steps?

General.pm

How about this stripped down version?

        expr X//1/3/// : 'X\(.*[^/]\)//*[^/][^/]*/*$'

What does expr --version or -V say?  Do you have a means to identify it?
