Fixed the location for the Zlib sed in the perl build. Thanks to Roy Bekken for seeing this and suggesting a fix.

I took this fix one step further and noticed that the sed was putting /usr/include in the libdir field. Updated it to use /usr/include only for headers and /usr/lib{,32,64} respectivly for libraries.
