No additional library is necessary.

Here is the procedure to install Exonerate from source code:

• The source code archive has been downloaded from its web location, decompressed in /home/bioubuntu and the resulting folder moved to /opt/bio/sources/.

• The /opt/bio/sources/exonerate-2.2.0 folder should belong to root and its permissions set to 755.

% sudo chown -R root:root /opt/bio/sources/exonerate-2.2.0

• Once yo uare in /opt/bio/sources/exonerate-2.2.0, compilation is easily done:

% sudo ./configure && sudo make

• To make sure that everyone can use it:

% sudo ln -s /opt/bio/sources/exonerate-2.2.0/src/program/exonerate /usr/local/bin/exonerate
