gsl_odeiv_evolve_apply

Hello

I've got an older version of GSL (version 1.5) installed on one machine
and a newer version (1.8) on another.  I can use gsl_odeiv_evolve_apply to
solve a single ODE with the older version but not with the newer
(gsl_odeiv_evolve_apply exits with an error).  Has this been purposely
changed?  Must I instead use numerical integration to solve single ODE's
in later versions of GSL?

Thanks!
Brian
