  Since you mention mingw32, I suppose you are on Windows.

  The Makefile used to build the 'binary for Windows' version of all
  the packages at CRAN/bin/Windows-NT/contrib (the directory is
  managed by Brian Ripley) is included in the rwXXXXsp.zip bit
  of the binary distribution. You should also look to file readme.packages
  included in the same archive.
  This assume that you have organized the source tree for the package
  as required by R. But this is easy and, in any case, required if
  you plan to make your port available. Details on the needed structure
  are in the R-exts manual (e.g. available in pdf form in rwXXXXd1.zip).

  (ps) BTW, can you provide more details. On which system are you working
       (OS, version)? Which version of the compiler are you using?
       Which errors do you get when you try to load splancs.dll?
