+=item I am not root, how can I install a module in a personal directory?
+
+You will most probably like something like this:
+
+ o conf makepl_arg "LIB=~/myperl/lib \
+ INSTALLMAN1DIR=~/myperl/man/man1 \
+ INSTALLMAN3DIR=~/myperl/man/man3"
+ install Sybase::Sybperl
+
+You can make this setting permanent like all C<o conf> settings with
+C<o conf commit>.
+
+You will have to add ~/myperl/man to the MANPATH environment variable
+and also tell your perl programs to look into ~/myperl/lib, e.g. by
+including
+
+ use lib "$ENV{HOME}/myperl/lib";
+
+or setting the PERL5LIB environment variable.
+
+Another thing you should bear in mind is that the UNINST parameter
+should never be set if you are not root.

+=item I installed a Bundle and had a couple of fails. When I retried,
+ everything resolved nicely. Can this be fixed to work on first
+ try?
+
+The reason for this is that CPAN does not know the dependencies of all
+modules when it starts out. To decide about the additional items to
+install, it just uses data found in the generated Makefile. An
+undetected missing piece breaks the process. But it may well be that
+your Bundle installs some prerequisite later than some depending item
+and thus your second try is able to resolve everything. Please note,
+CPAN.pm does not know the dependency tree in advance and cannot sort
+the queue of things to install in a topologically correct sequence.
+For bundles which you need to install often, it is recommended to do
+the sorting manually. It is planned to improve the metadata situation
+for dependencies on CPAN in general, but this will still take some
+time.

We should give coverage for B<all> of the CPAN and not just the PAUSE
part, right? In this discussion CPAN and PAUSE have become equal --
