You can use a Kolmogorov-Smirnov test. See ?ks.test where there is an 
example with a gamma distribution. You will probably need to estimate the 
parameters  of the Weibull which you can do with fitdistr() in package MASS.

However, I don't know if the distribution of the KS test will be the same 
if some parameters are estimated from the data or not (apparently, 
ks.test() doesn't do any correction). Someone on the list can help here.
