See versions which are available:

Load one version into your environment and run it:

$ module load circos/0.69-9
$ circos

Notes from the sysadmin during installation:

$ cd /tmp
$ wget http://circos.ca/distribution/circos-0.69-9.tgz
$ tar zxf circos-0.69-9.tgz
$ cd circos-0.69-9

Circos needs some Perl modules, check which we satisfy already with our system Perl:

$ ./bin/circos -modules

Create a directory for custom Perl modules and install missing modules with cpanm:

$ sudo mkdir -p /export/apps/circos/0.69-9/lib/perl5
$ sudo chown -R aorth /export/apps/circos/0.69-9
$ cpanm -l /export/apps/circos/0.69-9 Math::Bezier Math::VecStat SVG Set::IntSpan

Test again:

$ PERL5LIB=$PERL5LIB:/export/apps/circos/0.69-9/lib/perl5 ./bin/circos -modules

When all module requirements are satisfied continue the installation:

$ cd /tmp/circos-0.69-9
$ cp -r * /export/apps/circos/0.69-9

Add install directory to PATH and PERL5LIB and try to run it:

$ export PATH=$PATH:/export/apps/circos/0.69-9/bin
$ export PERL5LIB=$PERL5LIB:/export/apps/circos/0.69-9/lib/perl5
$ circos -modules

Fix permissions:

$ sudo chown -R root:root /export/apps/circos/0.69-9
