I've written a small Perl script that uses the Bio::Seq and Bio::SeqIO packages. When I try to run the script on a linux-based server. I got a lot of errors which basically told me that BioPerl hadn't been installed.

I installed ActiveState Perl 5.26 locally and have taken care of most of the prerequisites in order to install Bio::Perl. Only XML::DOM::XPath remains a problem. After trying to install the package, I received the following error:

```

```

This error seems to be connected to t/test\_non\_ascii.t, as an earlier output of trying to run the command install "XML::DOM::XPath" gave the following error:

```
t/test_non_ascii.t .................... The encoding pragma is no longer supported. Check cperl at t/test_non_ascii.t line 10.
BEGIN failed--compilation aborted at t/test_non_ascii.t line 10.
  Looks like your test exited with 2 before it could output anything.
t/test_non_ascii.t .................... Dubious, test returned 2 (wstat 512, 0x200)
Failed 10/10 subtests

```

Does anybody know what the exact cause of the error is and how I can fix it?
