Dipping my toe into command prompts.. totally lost.
I’ve installed Homebrew, and attempted to install libjpeg and optipng via brew install libjpeg optipngand have run into errors. I’m not sure how exactly to describe them.. so here’s the code! I’m in Terminal on a Mac running OSX 10.6.7
Thank you SO much for the help.

It looks like an autotools configure failed.
Consider re-running the install with '-vd' to keep 'config.log' around:
brew install -vd jpeg
Gist 'config.log' and any error output when reporting an issue.
Remember to include your config information: brew --config
Also try:
`brew doctor` to check your setup for common problems.
`brew missing` to check installed packages for missing deps.

/usr/bin is in your PATH before Homebrew's bin. This means that system-
provided programs will be used before Homebrew-provided ones. This is an
issue if you install, for instance, Python.
Consider editing your .bashrc to put:
/usr/local/bin
ahead of /usr/bin in your $PATH.
Some brews install binaries to sbin instead of bin, but Homebrew's
sbin was not found in your path.
Consider editing your .bashrc to add:
/usr/local/sbin
to $PATH.
"Git" was not found in your path.
Homebrew uses Git for several internal functions, and some formulae
use Git checkouts instead of stable tarballs.
You may want to do:
brew install git
You have an "autoconf" in your path blocking the system version at:
Custom autoconf in general and autoconf 2.66 in particular has issues
and will cause some Homebrew formulae to fail.

Try downloading and installing the Xcode development suite: http://developer.apple.com/xcode/
That will provide gcc (complier) to build the software
