Evaluation of integral

Hi,

I work with Maxima version 5.18.1, front end: wxMaxima 0.8.2.



I find that Maxima handles with great ease extremely tedious and messy 

integrals like integrate(sqrt(tan(x)),x) and integrate(tan(x)^(1/3),x).



But I find that it stumbles on this integral:

integrate(1/((x-1)^(6/5)*(x+3)^(4/5)),x)

though the answer is a fairly easy one:

-(5/4) *(x + 3)^(1/5)/(x - 1)^(1/5).



Any suggestions on how I could get Maxima to evaluate it? Is there some 

package to be loaded?



Thanks!
