Prototype mismatch: sub main::head vs ($) at ...

[Aaron DeLoach]

The line that produces the error: "Prototype mismatch: sub main::head vs ($)
at line ..." contains a call to the LWP module as follows: "use
LWP::Simple;"

Why am I getting this error in the error log?

You have probably defined a function named "head" elsewhere in your
program. When LWP::Simple tries to export its function "head", Perl
reports a clash. Whether the function is defined in your program,
or imported from somewhere else is anyone's guess, since you show
no code.

Applying PSI::ESP: see the section 'CAVEAT' of perldoc LWP::Simple.
