How can it be that I cannot any more see the perl errors, but I see just:
Compilation error at /usr/share/perl/5.14/utf8_heavy.pl line 447.
Even slight error in my file, causes this error. It can be missing curly bracket or not declared string or something. This might be error in general in Perl to be solved.
But I cannot know which line number I have to search for. It becomes impossible working with perl.
