This would either indicate that you have not installed the port that provides lp_solve, or that the path where lp_solve is located is not in your PATH variable.

"port installed" would tell you what's installed. In this case, the port "lp_solve" should provide the program "lp_solve".

Since /opt/local/bin and /opt/local/sbin are in your PATH, that seems to be fine. They're in there three times each, so you may want to edit your bash startup files to reduce that to just once, but that would just be an optimization, and wouldn't explain your current difficulties.

MacPorts should not be discarding the previous state between each phase. Above, the reason it can't apply the patches to the source directory in the patch phase is that MacPorts has thrown away the source directory right before that phase. I've never seen it do that before. The only reason it should be doing that is if the portfile is newer than the work directory. Unless your filesystem is very strange, that shouldn't be the case here. Can you run Disk Utility's disk check on your disk and see if it's ok? Is there anything else you can tell us -- OS version, Xcode version, MacPorts version, what your startup disk's format is (HFS+? case-sensitive or case-insensitive? journaled?), whether there are any other disks or network volumes attached, whether your computer's clock is set correctly, etc. You could also try cleaning the port and trying again (sudo port clean lp_solve).
