R-beta: autoloading a required library

I wanted to use the dist() function from the mva library in my own
library, so I put require(mva) in my files. When my library loads, a
message about "Autoloading ... mva" appears. But when I call dist() now
within my functions the message

Error in .C("dist", as.double(x), nrow(x), ncol(x), double(len),
as.integer(method)) : C/Fortran function not in load table 

appears.

After dyn.load("..._path_to_/mva.so") it works.

It's probably something wrong with the setup, but I don't know what. It
seems to work in my installation of R which is roughly 0.50a4.

Does it work if you use library(mva) instead?  This should be identical
except that it gives an error if "mva" doesn't exist, rather than a
warning.

and even if the require() is inside a function

ff<-function(x) require(mva)
is.loaded("dist")

[1] FALSE

ff(1)
