[Rd] include dll in R-package

We have several projects in the center done by researchers over years
in Fortran, there are copy right issues etc to prevent us from
giving away the source codes, but a lot of social scientist are 
interested to use the program. We tried to use dlls to make plugins 
(available in our website) in various statistics platforms 
(SAS, STATA and R) to make it available to general public.

We used to be able to build R package using dll on version R-2.7.0,
, but failed to build with newer R version with the same source. 
Any help is greatly appreciated. 

When I try to build R package for newer version of R, I could build 
to get "lcca_1.0.0.tar.gz", but when I "R CMD check lcca_1.0.0.tar.gz", 
I got error message as:

* using log directory 'D:/project/LCCA/lcca.Rcheck'
* using R version 2.15.1 (2012-06-22)
* using platform: i386-pc-mingw32 (32-bit)

See 'D:/project/LCCA/lcca.Rcheck/00install.out' for details.
and the message in 00install.out is:

Thanks a lot!
