The libintl-perl
package is platform independent but is not
part of the Perl core. The programmer is responsible for
providing a dummy implementation of the required functions if the
package is not installed on the target system.

The xgettext
parser backend for Perl differs significantly from
the parser backends for other programming languages, just as Perl
itself differs significantly from other programming languages. The
Perl parser backend offers many more string marking facilities than
the other backends but it also has some Perl specific limitations, the
worst probably being its imperfectness.
