For dh_make to find the package name and version, the current directory 
needs to be in the format of <package>-<version>.  Alternatively use the
-p flag using the format <name>_<version> to override it.
I cannot understand the directory name or you have an invalid directory name!

Your current directory is $pwd, perhaps you could try going to
directory where the sources are?

Please note that this change is necessary ONLY during the initial
Debianization with dh_make.  When building the package, dpkg-source
will gracefully handle almost any upstream tarball.
