geoffleach has asked for the wisdom of the Perl Monks concerning the following question: 

perl5 (revision 5 version 26 subversion 2)
linux 4.15.3-300.fc27.x86_64

[download]
new install

IO-Prompter-0.004014-0

perl -e 'use IO::Prompter'

[download]
Want.c: loadable library and perl binaries are mismatched (got handshake key 0xdb80080, needed 0xde00080)

I understand what this means. What I can't figure out is the offending library

Any ideas? Strategies?

Thanks.

    Want.c is created when installing Want, i.e. when compiling Want.xs. It's needed by Contextual::Return which is a dependency of IO::Prompter.

    ($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

      With cpan, I did a force install of Want and Contextual::Return. That resolved the issue.

      Many Thanks.

    Do you have different versions of perl installed in parallel? Perhaps, you need to recompile with a clean environment?

    Does strace -e trace=open perl -e 'use IO::Prompter' shed some light?

    Also inspect $ENV{PATH} and $ENV{LD_LIBRARY_PATH} and ldconfig -p.
