It seems that all current CAS have a problem with this integral:

fricas
(1) -> integrate(1/(-3+v^3)*v/(-4+v^3)^(1/2),v)
>> Error detected within library code: Not integrable (provided residues have no relations)

However, at least the error message could be better...

better error message? --wyscc, Sat, 08 Sep 2007 15:19:10 -0500 reply
