[Rd] Package compile under Windows on 2.6.0

[Iago Mosqueira]

Dear all,

We are experiencing some trouble when compiling R packages using R
2.6.0 and the new Rtools installer under Windows XP.

(1) First, compiling any package using the new setup stops with an
errorrelated to some "/" issue on the inst folder. This folder only
contains a CITATION file

(2) Testing with the previous Rtoolset with updated MinGW and Perl, a
package from CRAN can be compiled (VR), but our package now fails with

methods is loaded trhough a require(methods) inside an .onLoad call.

(3) The package compiles on a Linux machine with R 2.6.0

Is there any issue with MinGW or the Rtools he should consider?

Many thanks,
