Unable to install gcc46 +universal on 10.6.8 server

[petrsnd@…]

I want to install gcc46 on Mac OS X Server 10.6.8 Snow Leopard.

I issued the command:

port install gcc46 +universal

When installing the isl dependency it just fails. It complains about a directory that already exists. If I try to install isl separately, I receive the same result, even with the force flag:

port -f install isl +universal

I tried to clean isl and then rebuild it, but it also failed:

port clean isl && port install gcc46 +universal

Here is the failure output during the staging of isl into destroot:
