Squeak requires several libraries and tools. Install them via Portage:

emerge -av dev-libs/libjpeg media-libs/libpng media-libs/freetype x11-libs/libX11 x11-libs/libXext sys-libs/zlib sys-devel/libffi

Obtain the Squeak source code (e.g., from [SqueakSource](http://www.squeaksource.com/)):

cd /usr/src
wget http://www.squeaksource.com/Squeak5.6/Squeak5.6-src.tar.gz
tar xzf Squeak5.6-src.tar.gz
cd Squeak5.6-src

Configure, compile, and install Squeak:

./configure
make
sudo make install

Check if Squeak is installed:

which squeak

Run Squeak:

squeak

If you need a pre-built Squeak image (e.g., for a ready-to-run environment):

cd /usr/share
wget http://www.squeaksource.com/Squeak5.6/Squeak5.6.image

• **Dependencies**: Ensure all required libraries are installed (e.g., `libjpeg`, `libpng`, `freetype`, `libX11`).
• **Build Time**: Compilation can take hours on older hardware.
• **Troubleshooting**: If missing libraries appear, install them via `emerge`.

This process compiles Squeak from source. For a pre-built binary, check if Gentoo overlays (e.g., `squeak` overlay) provide an ebuild.
