Hi, I had a problem compiling it with perl 5.004_04 -- does it require
a newer version of perl?  I think I may have asked this before but
can't remember specifically what the answer was.

 Brian Gough (bjg@network-theory.co.uk) was saying:

I was able to get it to compile on my old version of perl by changing
T_UV to T_IV in the typemaps.  Apparently there was no entry for T_UV
in the standard perl typemap for 5.004.  The definition for T_UV in
later versions seems to be the same as for T_IV however --- they both
silently convert negative values into unsigned values.  Maybe it would
be worthwhile to provide a custom typemap entry that gives an error
when a negative value is used for an unsigned argument.

Math::Gsl 0.06

The new version of the perl API to Gsl has been accepted by CPAN into the
Math::Gsl namespace. To install:

perl -MCPAN -e "install Math::Gsl"

To view online documentation: http://leto.net/code/gsl/

There is a totally new API, which allows you to do all of the following:

        use Math::Gsl::Sf qw(:Gamma);
        my $sf = new Math::Gsl::Sf;
        my $r = new Math::Gsl::Sf::Result;

        print "1: Gamma(5): " . Math::Gsl::Sf::gamma( 5 ) . "\n";
        print "2: Gamma(5): " . $sf->gamma(5) . "\n";
        print "3: Gamma(5): " . gamma(5) . "\n";
        print "4: Gamma(5): " . Math::Gsl::Sf::sf_gamma(5) . "\n";
        my $status = $sf->gamma_e( 5 , $r );
        print "5: Gamma(5): " . $r->val . ",". $r->err ." $status \n";

Let me know what you think.
