Check for some perl modules. These are the modules needed by the core barnowl. We should probably eventually check for the ones Jabber and IRC need, too. Reviewed-by: Anders Kaseorg <andersk@mit.edu>

5# SYNOPSIS
6#
7#   AX_PROG_PERL_MODULES([MODULES], [ACTION-IF-TRUE], [ACTION-IF-FALSE])
8#
9# DESCRIPTION
10#
11#   Checks to see if the given perl modules are available. If true the shell
12#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
13#   ACTION-IF-FALSE are run. Note if $PERL is not set (for example by
14#   calling AC_CHECK_PROG, or AC_PATH_PROG), AC_CHECK_PROG(PERL, perl, perl)
15#   will be run.
16#
17#   MODULES is a space separated list of module names. To check for a
18#   minimum version of a module, append the version number to the module
19#   name, separated by an equals sign.
20#
21#   Example:
22#
23#     AX_PROG_PERL_MODULES( Text::Wrap Net::LDAP=1.0.3, ,
24#                           AC_MSG_WARN(Need some Perl modules)
