Source (any of the supported platforms)
$ svn co http://clam-project.org/clam/trunk clam
Test Data (Any of the supported platforms). Used in automatic back-to-back tests (you problably won't need this one unless you are developing CLAM)
Or, better, use the last version of the test data from subversion
$ svn co http://clam-project.org/clam_data/trunk clam_data
You can also browse for other CLAM related data packages
In older CLAM releases we used to offer the external libraries for download including Windows binaries. They can still be found here though they might be oldish versions and we recommend to download the external libraries from their official pages.
