[Slashcode-general] Perl bug under slashcode install

[Flemming B. <fl...@bj...>]

There was a bug in a Perl module under installation of slashcode 2.5.2
(on a debian squeeze stable).

> install Bundle::Slash
......
/usr/bin/perl t/TEST
local/compatibility.t .. Can't locate object method "parse_head" via
package "LWP::Parallel::Protocol::http" at
../blib/lib/LWP/Parallel/UserAgent.pm line 1497, <DAEMON> line 1.
Missing base argument at local/compatibility.t line 57
.....
.....
MARCLANG/ParallelUserAgent-2.57.tar.gz
/usr/bin/make test -- NOT OK
...............

The bug is described here, where you also find a patch:
http://rt.cpan.org/Public/Bug/Display.html?id=40261

To fix it, the module ParallelUserAgent must be downloaded:
http://cpan.uwinnipeg.ca/cpan/authors/id/M/MA/MARCLANG/ParallelUserAgent-2.57.tar.gz

After unpacking, line 1496 in UserAgent.pm should be changed from:
   $protocol->parse_head($parse_head);
to:
    $protocol->can('parse_head') ?
    $protocol->parse_head($parse_head) :
    $protocol->_elem('parse_head', $parse_head);

Then compile and install the ParallelUserAgent module as describes in
README. Finally, you can go back to the perl prompt and run again:

> install Bundle::Slash

and no errors should come out.
