At last after a long fight I figured it out. It was due to defining the egal sub which is like: 

sub egal () {
     # ....
}

# Rather than: 

sub egal {
     # ....
}

[download]

This was imposing argument prototypes on egal (i.e. no args). This was the reason why Perl can't find the sub when an argument is passed.
