HOWTO: Install FrostWire
From Sabayon Wiki
Getting FrostWire to work on Sabayon Linux has been a frustration up until now. By following the steps below you'll have FrostWire working in a matter of minutes.
Step 1. In a terminal, become root.
su
Enter your root password when prompted.
Step 2. Emerge Sun's Java.
# emerge sun-jre-bin
Step 3. Emerge FrostWire.
# emerge frostwire-bin
Step 4. These steps are borrowed from the Compiz-Fusion Update Guide.
# echo "x11-libs/libX11 xcb" >> /etc/portage/package.use # emerge x11-libs/libX11 # CFLAGS="-DNDEBUG" emerge x11-libs/libxcb
Step 5. Make the FrostWire run script executable.
# chmod +x /usr/share/frostwire/runFrostwire.sh
Step 6. Click on the FrostWire entry in your menu, or just type "frostwire" (no quotes) in your console (as a regular user) and hit enter. It should work now.
