Exception UnsatisfiedLinkError when running under Linux

I have a very light test project stored in Integrity.
SCM commands (like "scm:status") ran against this project under windows work well.
If I check-out this same project under Linux environment (with an MKS client 2009 configured properly), I get the following error when running scm:status (or any other command) :

[INFO] [scm:status

Here no credentials were provided in the SCM connection url, but providing credentials lead to the same error.
A command "si connect" issued under same environment with same parameters (hostname, credentials...) connects successfully to MKS.
