Problem installing readline

Hi, i have a iMac G5 17" PPC. I am trying to install readline, but i get these errors : ---> Staging readline into destroot Error: Target org.macports.destroot returned: no such file or directory Error: Status 1 encountered during processing. However on my intel macbook it worked fine. But i cant get it to work on my PPC. Both Computers have Mac OS Tiger 10.4.10 Installed. Anyone knows what to do ? Best Regards Tom
