Well i realized i didn't need to "clobber" anything to put that opt directory in my root, i guess because it is in root instead of /usr/local/opt then it takes precedence for those files? is that the idea?
Well i gave up on compiling due to those errors, but the binary version is running, i'm at 27 shares in little under 15 minutes, i only got 27 shares in several hours on ypool last night. so this is definitely a major improvement. thanks for your work!
