Bionode should compile automatically samtools so you don't need to. bionode-sam is using a shell script (build.sh) so that's why it's not working on Windows. However, even in Linux/OSX, this is still currently prone to fail (see #29) so we are considering alternatives for wrapper modules that require binaries. The other modules (e.g., bionode-ncbi) should work.
I'm closing this, please feel free to discuss it further on #29.
