# su -c 'perl -MCPAN -e "install DBI"'
# su -c 'perl -MCPAN -e "install DBD::SQLite"'

Plan:
1. Write a Perl program with _very_ simple dependency checking.
2. Make notes on ldconfig
3. Make notes on various packages, e.g. OpenSSL

Note about /sbin/ldconfig:
The ldconfig man page (ldconfig(8) states that "ldconfig ignores symbolic links
when scanning for libraries." What does this mean?

Stowing OpenSSL
I ( Troy Will April 2009 ) did a ./config --prefix=/usr/local shared && make &&
  make install of OpenSSL. With Stow could not find the shared libraries with
  ldconfig -v. Installing directly without Stow, I was able to find the shared
  libraries with ldconfig -v.
