I got it and I can confirm to get warnings / errors along these
lines, also with today's  "R-1.9.0 alpha"

(so just delete these two directories for now; but that doesn't
 help for the real problem below !)

Yes, unfortunately, you don't get better errors here.

     [[ -> feature request ;-) ]]

But since "R CMD check" *does* install the package , you just
load/attach it manually 
(using 'lib.loc = "..." !) and can see what the matter is :

  > library(distr, lib.loc="/u/maechler/R/other-people/distr.Rcheck")
  Error in loadNamespace(i[[1]], c(lib.loc, .libPaths()), keep.source) : 
	  package 'stepfun' does not have a name space
  Error in library(distr, lib.loc = "/u/maechler/R/other-people/distr.Rcheck") : 
	  package/namespace load failed


Now this does help you further.
Particularly for the above case, I'd recommend to

** Get and install "R-1.9.0 alpha" and exclusively work with R-1.9.x
** for the "distr" package.

Reason: From 1.9.0 on, "stepfun" is part of "stats"  
	- which *is* a namespace
	- and a "default package", i.e. you don't even have to
	  say "library(stats)" by default.

With high regards to the "distr" developers,
