If you can build something from source, you should do that. If it doesn't do the job, try the binary blob instead. And from what I've seen, it really depends on the device and boils down to trial and error. Device vendors sometimes make changes to the device drivers without releasing the source code. Regarding vold, I'm surprised that it gave you trouble. There's nothing apparently vendor-specific about SD-card management. Could it be that it's just outdated? Did you try to build with a different tag/branch instead?
