i was fully prepared to whine about being in the dark on "how the hell
can you find the package to download when you just know about one
missing file?"
well, i solved it myself, so thought i'd share the process...
(i'll get to whine later about something else, i'm sure.)
i'd changed some stuff in the config files for apache, so i
wanted to reload the settings:
# apachectl graceful
it whined about troubles, and suggested i try:
# apachectl configtest
Syntax error on line 100 of /etc/apache/httpd.conf:
Cannot load /usr/lib/apache/1.3/mod_perl.so into server:
/usr/lib/apache/1.3/mod_perl.so: cannot open shared object file: No
such file or directory
WHAT? modperl is gone? how can apache even RUN without modperl? aaugh!
that's like a face without a skull! or a skull without a brain! or
a brain without a mind! or a mind without a purpose!
so i tried
# apt-get --reinstall install modperl
# apt-get --reinstall install mod_perl
# apt-get --reinstall install mod-perl
but it didn't find any of those.
(i was shooting in the dark, can you tell?)
AHA.
here's how you find out what the bloomin' package names are...
# dpkg -S modperl
dpkg: *modperl* not found.
damn. seemed reasonable, but there are other permutations possible.
here i try "mod-perl" with a hyphen:
# dpkg -S mod-perl
libapache-mod-perl: /usr/share/doc/libapache-mod-perl/README.gz
libapache-mod-perl:
/usr/share/doc/libapache-mod-perl/examples/CVS/Template
[snip]
the mother lode! let's try one more permutation, just for giggles--this
time "mod_perl" with an underscore:
# dpkg -S mod_perl
libapache-mod-perl: /usr/share/man/man3/cgi_to_mod_perl.3pm.gz
libapache-mod-perl:
/usr/lib/perl5/5.005/i386-linux/mod_perl_method_handlers.pod
libapache-mod-perl: /usr/lib/perl5/5.005/i386-linux/mod_perl.pod
[snip]
the father lode!
so now i know to ask for "libapache-mod-perl"...
# apt-get install libapache-mod-perl

so it also set-up other items that i needed, as well (just like it
says in the docs!) all of which i'd already downloaded. i know that
no downloading was necessary because it confirms that you really
wanna download before doing so, and it said

so i confirmed that i wanted to install, though no downloading was
needed. very cool.
that's how i got past the hurdle of missing crucial components.

now i just gotta figure out where the apache settings are that are
keeping all my cgi's from working.
