Hi
If you go down the route of compiling the latest perl from CPAN, there are
detailed installation instructions in the INSTALL file with the source. Your
current perl would be installed somewhere like /usr/local/perl5.6.8 with the
perl executable simlinked to /usr/bin/perl or somesuch.
You can specify the directory into which the newly compiled version will be
installed at compile time (follow the details in the INSTALL file) - use
something like /usr/local/perl5.8.7 then you can simlink to the executable
with something like /usr/bin/perl5.8.7
Any perl script that you use will have a first line which tells it the path
to the perl interpreter it should use - such as #! /usr/bin/perl
In this case you would change the corresponding lines in your spamassasin
script to #! /usr/bin/perl5.8.7
All you old scripts will use the old version - only spamassasin will use the
new one.
If anyone knows a simpler way - or spots an error, please feel free to
correct me.
Hope it helps.
