I don't think so. A required version mismatch would look like the following: 

>perl -e "use CGI 9.99
CGI version 9.99 required--this is only version 3.20 at -e line 1.
BEGIN failed--compilation aborted at -e line 1.

Looks more like a descrepency between the version of the .pm and the associated XS object file(.so/.dll).

Also, the error is for PerlIO::scalar, not IO::Scalar. Since PerlIO::scalar is a core module it means his Perl installation is messed up.
