Then let me ask this:
I suppose this will be the final version of PP for perl-5?
If so, then for those of us who have that new version (me, amazon
tonight), on the errata page, periodic (and separate) new-feature
files, that we can print out and stick in the book next to the
various pages to be updated?
And Brian, thanks for all the hard work you guys took on, updating
that MONSTER book. (Reading it: drinking from a fire hose!)

I don't see why you would say that. Perl 5 development is likely to
continue for the forseeable future. The original Plan, that 5.10 would
be a dual perl/ponie release, and 5.12 would be ponie-only and the last
release of Perl 5, is long gone. (Ponie was the plan to port Perl 5 to
Parrot, the Perl 6 VM. It was abandonded after a substantial amount of
work, because it doesn't appear to be possible to make the XS interface
work with anything less than genuine perl 5.)

THANK YOU!!!!
Programming Perl: what happened to Larry (as author)?
Now, let's go back a couple of years: how about in 2011
and 2010 (or even 2009 and 2008).
THANKS AGAIN!
Now I go buy them (amazon).

Thanks.
What's your publisher list?
(Also, nerdbooks.com does have a list of new books, but I sure
haven't noticed either Modern Perl or PP #4. Better look again!)

I have no admin rights to compile perl and I guess I'd need them. What do you mean by getting function names? I'm not sure how this whole backtracing works in perl.

To get a backtrace from you current binary, make perl crash, locate the
core file, then run
gdb /usr/bin/perl ./core
gdb> bt
Adjust the path to the perl binary and to the core file as appropriate.
If you don't get a core file you may need to change your ulimit, or you
can run
gdb --args /path/to/perl /path/to/script
gdb> run
which will run perl under the debugger from the start. If you don't have
gdb, but you do have some other C debugger, you can probably use that
instead, but you'll have to read its documentation to find out how.
Rebuilding perl doesn't require admin rights. *Installing* perl into a
system directory (/usr/bin or /usr/local/bin) does, but it's perfectly
possible to install it under your home directory, you just have to pass
the appropriate -Dprefix= option to Configure. (I have about a dozen
versions of perl installed under my home directory at the moment, which
I use for testing code works properly across different versions.)
For something like this you probably don't need to install it at all:
just build perl and run it from the build directory (./perl -Ilib ...).
If you want to try (and, given your apparent inexperience with this sort
of thing I wouldn't blame you if you didn't), start by downloading the
perl source from perl.org and reading the INSTALL file.
