8.1 Perl Thread issues

If mod_perl is to be installed (regardless of the SSL status), and if Perl, on the system, was installed with -lpthread, the following will have to be passed to the Apache configure script, that will be outlined in the next section:

# CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" \
    LIBS="-lpthread" \
    ./configure ........

One can always tell if they have a thread-enabled version of Perl by checking the version:

# perl -v

This is perl, v5.8.3 built for i386-linux-thread-multi

Without the mention of threads, it is alright to proceed as normal without mentioning the LIBS line as above.
