AC_PERL_MODULE_VERSION([MODULE VERSION], [ACTION-IF-TRUE],
[ACTION-IF-FALSE])
Checks to see if the list of 'Module Version' are avaiable in the system. If all the modules in the list are avaiable ACTION-IF-TRUE is executed. Case one module is not avaiable ACTION-IF-FALSE is executed and the macro execution is aborted. NOTE: Perl is needed.
Example:
AC_PERL_MODULE_VERSION(CGI::Test 0.104 CGI::Ajax 0.694, ,
AC_MSG_ERROR(Need some Perl modules))
