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 


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

Is there something wrong with the autoloading process or should 
statements like `if (!is.loaded("dist")) {dynload("mva.so")}` be added to 
the functions of the mva library? Or is this problem due to a wrong setup
in my R (0.50a4)?
