Error in the installed software

Once doxygraph is installed, running it you get this error

Bad path specification: lib' =>/usr/local/bin/lib' (No such file or directory) at /usr/local/bin/doxygraph line 9.
BEGIN failed--compilation aborted at /usr/local/bin/doxygraph line 9.

The error is in the line:

use lib::abs 'lib';

This because the directory doxygraph-master/doxygraph/lib is not copied to /usr/local/bin/, so the script does not work.

I solved manually by copying the contents of doxygraph-master/doxygraph/lib in /usr/local/lib and changing the content of /usr/local/bin/doxygraph as follows:

9c9
< use lib::abs 'lib';

---
> use lib::abs '/usr/local/lib';
