Here's what's on my 5.8.8 with fPIC, I haven't tried 5.10.1 on 64 bit yet.
cc='cc', ccflags ='-fPIC -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -I/usr/include/gdbm',
I'm not sure if the perl you showed me below has fpic configured.
I recommend that you compile a non-threaded version of perl though in
a separate installation location (with fpic configured of course), and
then build mod_perl from that. I usually use /home/app_user/perl.
There are a couple of reasons to do this:
1) If you start using CPAN with an rpm based distribution such as
centos, then you will be installing modules that should be installed
via RPM. The Fedora maintainer gave a note on this in a talk a couple
years ago at YAPC Chicago.
2) Single threaded perl binaries tend to be faster (~20%) and more
stable than threaded perl binaries. I don't have the data to post,
but I did some perlbench comparisons a few years ago with 5.8.8. This
may have changed with 5.10, but I would consider it unlikely.
3) You can ensure that you have fpic configured.
