[racket] planet package with DLLs

Hi,

I have a package that I uploaded to planet that depends on
some DLLs. I included these DLLs in the package but they,
in turn, depend on the presence of the C++ runtime DLLs,
namely msvcp100.dll which some systems already have
and some others don't.

What is the recommended practice for including DLLs with
planet packages so that users can simply require the planet
package and everything gets installed properly?

Is there a planet package that already solves this problem
that I can study?

Best,
António.
