CPAN Update of File::Temp Doesn't Update
CPAN downloads the current File::Temp version (0.20) and successfully builds it and installs it into the expected location pointed to by the PREFIX. It then re-attempts to build HTTP::Body which fails with the same error
This looks like %ISA isn't updated after building and installing the new File::Temp. CPAN requires
File::Temp to get at its version, downloads the new package, builds and installs it, then goes to
build HTTP::Body - still having the old File::Temp loaded.
Quitting the CPAN shell after having installed File::Temp and invoking it again to install HTTP::Body
