Failed to install libgcc9: no destroot found

[Vahid Askarpour]

I tried the advices from Ryan and Chris, cleaning the ports and reinstalling Macport without reinstalling the OS. This time, the installation of xcrysden was complete, no errors and xcrysden is working fine. In my earlier attempts, I did not clean the ports and this might be the key factor. 

Many thanks for all your comments.

You can find each attempt by searching through the logfile for "version:1". It might also be useful for the user to "sudo port clean" the affected port before trying again, to ensure that the prior incomplete attempts are not interfering.
