It exits with the following error message:

The file libperl.a does exist on my machine. perl -V:libperl produces
"libperl='libperl.a'". So I am assuming that libperl is installed.
perl -V produces the following output:

Looks like a broken perl to me.
What happens when you run the following script:
#######################
use warnings;
use Inline C => Config =>
BUILD_NOISY => 1;
use Inline C => <<'EOC';
SV * foo() {
return &PL_sv_yes;
}
EOC
print foo();
#######################
For me, it builds fine and then prints 1.
Btw, whether or not libperl.so should exist depends upon how perl was built.
(It doesn't exist for most of my linux builds.)
I think the way to tell is to run 'perl -V:libperl'. If that reports
'libperl.so', then that file should exist (in something like
/usr/local/lib/perl5/5.8.6/i686-linux-thread-multi/CORE/libperl.so). But if
it reports 'libperl.a', then I don't think libperl.so should exist. (But I'm
not an expert on linux.)
Probably best to send us the output of 'perl -V', which should tell us all
we need to know about how your prl was built.
Cheers,
Rob
