If instead, you did this: cd /source/pltosx make make install you'd re-use the binaries. Officially, this isn't supported because the dependency tracking in the source tree is complex and not quite right. But, in practice, it works 90% of the time. It won't work when any of the makefiles change or when configure changes. If it doesn't work, you can just do the below. Your preferences file won't be affected. DrScheme uses the same one, regardless of the build directories or the version of DrScheme (a few preferences, like the language setting, are version-specific, tho). hth, Robby </blockquote> Thanks for the tip Robby, Everything went smoothly and quickly. <pre class="moz-signature" cols="72"> --kyle Kyle Smith airfoil at bellsouth dot net schemekeys.blogspot.com </pre> </body> </html>
