Hi, in order to repair my port-system I removed completely the whole software-branch "/opt" and reinstalled MacPorts (1.52 on my Intel- MacBook with Mac OS X 10.4.10). I installed the window-manager ratpoison as first port. "port installed" gave me the list with one element as expected. Then I installed gcc43 ("sudo port install gcc43"). The build was successful (including the libs), but at the end I got: ================ ---> Building gcc43 with target bootstrap ---> Staging gcc43 into destroot ---> Installing gcc43 4.3-20070907_0+darwin_8 list must have an even number of elements Error: Status 1 encountered during processing. ================ I cleaned gcc43 ("sudo port clean gcc43"). And then: ================ port installed Error: port installed failed: list must have an even number of elements No ports are installed. ================ What can it be? Eckhard.
