As Mark Rivers already said there are no build error messages in the
above output, so I don't think there is anything wrong with your build.
You seem to be compiling for two target architectures, linux-x86 and
linux-686. The Perl CA bindings in src/cap5 are only supposed to be
built on the host architecture (x86 in your case) where they succeeded
as shown in the first lines above. You should be able to use them from
the linux-686 architecture if you actually need them because the
libCap5.so library gets installed into a Perl-version-specific directory
(which in your case is .../lib/perl/5.10.1/i386-linux-thread-multi)
which should be the same directory for both targets.

By the way, I would not generally recommend building EPICS (or any
software really) as the root user, it is much safer to use a regular
user account, giving that account write access to the installation
directory tree if necessary.
