[pca] pca --man

[French, David]

I had a similar problem, the fix is everyone needs read access.  For security Pod::Usage won't run as root.  pca switches to user nobody before calling it.  From the pca code:
 
  # Change uid to something secure as pod2usage does not run as root.
  # This snippet is taken from perldoc. See the comments there.
  my $id= eval { getpwnam("nobody") };

Hope this helps.

	What are the overall permissions?  The line shown is trying to open a file for read access, do you have read access for pca.  I would say you want something between 500 and 555 for pca.

	Hi everyone,
	 
	I have the follwoing problem if I try to open the manual for pca:
	 
	pca --man
	Can't open /bin/pca: Permission denied at /usr/perl5/5.8.4/lib/Pod/Perldoc.pm line 1371.
	
	I´m logged in as root and /bin/pca has x permissons.
	 
	Here is line 1371:
	 
	1370      local($_);
	  1371      open(TEST,"<", $file)       or die "Can't open $file: $!";   # XXX 5.6ism
	  1372      while (<TEST>) {
	  1373          if (/^=head/) {
	  1374              close(TEST)         or die "Can't close $file: $!";
	  1375              return 1;
	  1376          }
	  1377      }
	  1378      close(TEST)                 or die "Can't close $file: $!";
	  1379      return 0;
	
	 
	Any suggestions ?
	 
	Thank you.
	 
	Regards
	Robert
