How can I specify the version of Python that Perl's Inline::Python module is using?

Question

I am running Debian squeeze and perl v5.10.1 and I have two versions of python installed:

$ pyversions -i
python2.5 python2.6

Python::Inline uses python2.5 obvoiusly:

$ perl
use Inline::Python;
Inline::Python::py_eval('import sys');
Inline::Python::py_eval('print sys.version');

2.5.5 (r255:77872, Nov 28 2010, 17:10:16)
[GCC 4.4.5]

I need python2.6 to run my python code. How can I accomplish that?

You link with desired version during the installation of the module. See Makefile.PL:

#============================================================================
# What python are we going to try?
#============================================================================
my @pythons;
my $sep = $^O eq 'MSWin32' ? ";" : ":";
for $p (split /$sep/, $ENV{PATH}) {
    $p =~ s/^~/$ENV{HOME}/;
    $p .= "/python";
    push @pythons, { path => $p } if -f $p && -x $p;
}

# Keep them in PATH order.
#@pythons = sort { $a->{path} cmp $b->{path} } @pythons;

my $num = 1;
print "Found these python executables on your PATH:\n";
print $num++ . ". " . $_->{path} . "\n" for @pythons;

my $sel = prompt("Use which?", '1');
$sel = $pythons[$sel-1] if $sel =~ /^\d+$/;
$sel = { path => $sel } unless ref $sel eq 'HASH';

print "Using $sel->{path}\n";
