No additional library is required.

You have to register on the website to get access to the executables and/or the source code (by contacting the author). Here is the procedure to install PhyML using the executable:

• The archive with the various executables is downloaded in /home/bioubuntu, decompressed and the newly created folder moved in /opt/bio/sources.

• This folder should belong to root and its permissions set to 755.

% sudo chown -R root:root /opt/bio/sources/PhyML_3.0
% sudo chmod 755 /opt/bio/sources/PhyML_3.0

• Once you are in /opt/bio/sources/PhyML_3.0, you simply have to make sure that the executable is available to all:

For x86_32 systems:

% sudo chmod ugo+x /opt/bio/sources/PhyML_3.0/PhyML_3.0_linux32
% sudo ln -s /opt/bio/sources/PhyML_3.0/PhyML_3.0_linux32 /usr/local/bin/phyml

For x86_64 systems:

% sudo chmod ugo+x /opt/bio/sources/PhyML_3.0/PhyML_3.0_linux64
% sudo ln -s /opt/bio/sources/PhyML_3.0/PhyML_3.0_linux64 /usr/local/bin/phyml
