Dmitry, am I right that this:
> openat(AT_FDCWD,
> "/usr/local/lib/x86_64-linux-gnu/perl/5.34.0/auto/Prima/Prima.so",
> O_RDONLY|O_CLOEXEC) = 5
was output from your locally running the strace command?
I believe Ingo thought that was a snippet of Perl he was supposed to run, but I
think it’s instead strace’s output in (close to) C.
Best regards,
Ed

Great! I'm really curious what was than system... could you possibly send me
(ok if personally, too)
output of `uname -a` and `cc -v` ?

I'm not sure I follow the question. Do I understand correctly that if you run
this from bash
$ perl -Iblib/arch -Iblib/lib -MPDL::Drawing::Prima -e 1
you get syntax errors?
