Non-uniform randomness in Erlang? (as a feature)

Hi,

A bit in link with the recent message of Kenji regarding 
state-of-the-art random generators: if needing to draw samples from, 
this time, a specific, non-uniform distribution, are there Erlang 
libraries able to accept as input such a user-specified, arbitrary 
probability density function?

(I searched for "Inverse transform sampling in Erlang" and alike, yet, 
because of the statistical distribution of the same name, pointers are 
difficult to find)

Thanks in advance for any information,

Best regards,

Olivier.
