Subject: perldoc search ., lib and blib/* if -f 'Makefile.PL'
From: Tim Bunce <Tim.Bunce@ig.co.uk>
Files: utils/perldoc.PL

    Subject: perldoc finds wrong pod2man
    
    (from perldoc source)
    
        # We must look both in @INC for library modules and in PATH
        # for executables, like h2xs or perldoc itself.
    
    Unfortunately, searching PATH for installed perl executables like
    pod2man is INCORRECT.  perldoc should start by searching the
    directory it was executed from, which might not be in the PATH
    at all.
