New description:

 It was great to port VLC to the last version and it runs really stable.
 Yesterday I tried to update my tree, but updating from 2.0.1 to
 VLC-2.0.1_1, the build failed.
 I cleaned then all installed ports and start the installation again, but
 was also not successful.

 Last lines of main.log:

Comment:

 The actual relevant error in the log appears to be:
