- Get libwww-perl from CPAN (http://www.perl.com/CPAN/modules/by-module/WWW/). W3mir does not work with LWP 5.40 and later versions. Please get an earlier version. It also does not work with the new URI package. Use the URI package enclosed in the older LWP. - Unpack it: gzip -dc libwww-perl-*.tar.gz | tar xvBf - - Install it. W3mir does not require the whole libwww-perl package and all the packages that goes with it to work so you may follow these install instructions instead of the libwww-perl install instructions to get an easier install which will work with w3mir. cd libwww-perl-* Are you going to install it in the standard perl place (you need to be the system administrator to do this)? If so: perl Makefile.PL If not (if you are a user): perl Makefile.PL PREFIX=/some/dir /some/dir could be ~ (as in your home directory). IF you are installing an old LWP just for w3mir you can install both the old LWP, the Base64 module and w3mir in a special PREFIX separate from your usual install PREFIX. This ensures that w3mir will access the older version of LWP and that other software will access the newer version. If you do this make sure you install all of LWP, Base64 and w3mir with the same PREFIX. This step might produce some complaints; A standard perl installation will typically get messages about missing these modules: IO::Socket, NET::FTP and MD5. None of these need be installed to run w3mir and so any error messages about these may safely be ignored. make make test (robot/ua and local/http might fail, that's OK) make install Now libwww-perl should be installed and working.
