lang/gcc compile errors to build the port

[Xavier]

Hi,

I updated the system port:

root at acer_casa_FreeBSD:/root # portsnap fetch update
Looking up portsnap.FreeBSD.org mirrors... 7 mirrors found.
Fetching snapshot tag from ec2-eu-west-1.portsnap.freebsd.org... done.
Latest snapshot on server matches what we already have.
No updates needed.
Ports tree is already up to date.

I have updated all ports:

root at acer_casa_FreeBSD:/root # portmaster -Da
===>>> Starting check of installed ports for available updates

===>>> All ports are up to date

===>>> Exiting
root at acer_casa_FreeBSD:/root #

I paste the last lines of compile errors:

There is just an opening of 20090912 ( for lang/gcc44 ) and I guess is
not relevant for this problem.
I haven't found any relevant information about this problem.

As a last resource I ask in this mailing list, if any can help me to
fix this problem.

See you.
