Graph-tool make error

I'm trying to compile graph-tool on CentOS 5.4 with boost 1.49.0, and I'm getting two errors

Just thought I'd upload the full output of make, although it looks scary:

Would very much appreciate if you could look into this.

Many thanks!

Update: I've now downgraded to 1.46.1, with which this error did not
occur. I've logged a ticket (#99) on the graph-tool website - perhaps
even if it's not worth the effort fixing this error, it'd be good to
warn users about it.
