[Mohsen Pahlevanzadeh]

Hello , When I‌ run publican version 4.3.2-4 on debian unstable, I get the following error message: ##################################### mohsen@debian:~$ publican Attempt to call undefined import method with arguments ("abs2rel") via package "File::Spec" (Perhaps you forgot to load the package?) at /usr/share/perl5/Publican/TreeView.pm line 12. Duplicate specification "help" for option "help" Can't open publican: No such file or directory at /usr/bin/publican line 646. ################################################# How can I solve it? Yours, Mohsen
