We have had Linux users that successfully used Ryacas but if you can't get yacas to build on your particular system then you could try running the Windows version under wine. A Windows binary of yacas is available so you won't have to build yacas. I don't know if anyone has tried that yet but its worth a try.
Another possibility is to try rsympy or rmathpiper (see introductory paragraphs on Ryacas home page for links).
