I had the same problem with IO::SCALAR install too. I found what I had to do was go to here:
http://search.cpan.org and then type in a search for SCALAR.PM. Choose the first result that comes up, it should be something like IO::SCALAR. Click it then click on the "source" link that is near the top of the page. Select all of that text and copy it into notepad. then save it to c:\perl\lib\io as scalar.pm. Next repeat the search but this time for WRAPTIE.PM. Next click the first hit back, should be something like IO::WRAPTIE.PM. Click the source link that is near the top again and now select all that text and copy it into notepad then save it as c:\perl\lib\io\wraptie.pm. This worked for me atleast. I found this solution in this thread:
