[R] Using win-builder with static libraries

[Uwe Ligges]

I may be able to help if you upload to winbuilder again and let me know 
when you did (don't have your source package any more).

I guess there are roughly 1-5 errors:

error 1: Where is the static library from? If copied from numerical 
recipes: Please do look if you have the right licenses.

error 2: Better ship sources rather than compiled code: it allows to 
build on more platforms. The static library will only work on the 
particular system (such as 32-bit Windows) it was compiled for.

error 3: Do you have the statistic library in pkg/lib or pkg/inst/lib ? 
You need the latter.

... more if you send the source package to allow us to look what you did 
(given you are allowed to distribite it).
