I believe in doing things properly, so I'll spin up a VM with Redhat 8.6 at some point today (or more likely this evening as it's looking like a busy day) and try and replicate what you're experiencing here.
You had no problem with the dnf perl bindings installation,
and only with the cpan installs,
from what I gather.
John's mentioning of version numbers reminds me - you can use cpan or cpanm to install specific versions of modules too.
If there's a known version that works well with your RedHat 8.6, you could ask cpan or cpanm to specifically install that version.
This is assuming I'm not confusing Perl Module versions with underlying lxslt versions.
I once had a problem running Alien::ImageMagick on an older version of CentOS, and found it was attempting to install a version of ImageMagick not compatible with my OS, so I just jumped into the part of the cpan module that
specified what version of ImageMagick to install, changed it to a last known working version, and that solved the problem, giving me a uniquely patched version of the cpan module to install to solve my particular issue.
Of course in this case, the error we're facing is it not being found. Which means there's a risk it could be there and working and just not being located.
Obviously I'm only speculating and could be completely wrong.
I'll replace hypothetical guessing with experience and results from trial and error,
when I get the VM going later today.
Of course, the problem could be something unique to your setup Maher, that I may not be able to initially replicate with a VM, and might be able to replicate with further communication with you. For now, I'll give it a go later
today, and see what I find, then I'll post back here and share any findings.
Feel free to experiment with other potential solutions in the meantime.
Or take a break if it's driving you potty ;-).
Yours,
Andrew.

Are there any other modification required to be made in the Makefile.PL file? As it is still complaining that libxslt not found??

It doesn’t look like the above commit has made it to a release version yet – but I’m not sure why that would cause the CPAN route to fail, unless the CPAN and DNF are different version numbers…

Hi Martin
The packages libxslt-devel libxslt libxml2-devel libxml2 are only installed using dnf and are not installed again on the system using CPAN. As for the XML::LibXSLT it is recommended in the documentation to install it using CPAN and not as an rpm using dnf.
Any ideas?
