irssi needs to be upgraded. This was out of my radar. It uses an 
embedded perl interpreter.

Yes.
But we'd need a full parallel perl-5.8 installation for this issue, not 
just the dll in a seperate libperl58 package, which could be added to 
the perl dependencies.

In theory I can prepare it, because I use dozens of parallel perls right 
now, to test various packages against older versions.
But I rather want to break older packages and force those to be upgraded.

BTW: For me irssi works fine, because I have the dll and the full 
library path.

No, we are not binary ABI compatible with 5.8 anymore.
We just can support only the non-XS packages.
But we cannot support packages linking to the old 5.8 dll and not 
packages using old 5.8 XS code.
