I'm submitting this bug report to Config and Pod::Usage, because I'm not certain which one needs to be changed to fix the problem. My perl is built with -Duserelocatableinc. Problem: When I call pod2usage( -verbose => 2 ), it tries to invoke "$Config{scriptdir}/perldoc". It fails because the value of $Config{scriptdir} is '.../'. I don't know if Config should have applied relocate_inc() to $Config{scriptdir} or if Pod::Usage should have used $Config{scriptdirexp}. I also noticed a related potential problem: Both $Config{bin} and $Config{binexp} have the value '.../'. Attached is the script 'pod2usage.pl' which demonstrates the problem, and also prints the %Config values I mentioned above. Sample run: $ perl ./pod2usage.pl scriptdir : .../ scriptdirexp : /apps/perl/5.14.2/bin/ bin : .../ binexp : .../ Also attached is a patch for Pod::Usage, should that be the correct solution. I did not attach a patch for Config. I don't know how to fix it, since I don't think I understand the intended difference between, e.g., $Config{scriptdir} and $Config{scriptdirexp} (given that they both existed before relocatable @INC). I am interested in clarification on this. Thanks very much for your time and effort. I am interested in knowing the proper fix for this problem.
