Re: mod_perl, compilation issues, cont

Thank you very much for your reply below. I was getting desperate of getting any at all.
I will check the permissions issue and post back to the list.

Maybe in the mneantime an additional question to the list : has *anyone at all* succeeded 
in installing (and using) Apache 2.4 / perl 5.20+ / mod_perl 2.x on a Windows 10 platform ?
Knowing that someone else has been able to do that, would already help me in focusing my 
debugging efforts to something specific to my laptop.
