root directory full

Hello

I have a problem / is full but I don't manage to see what takes the space.

x1# df

The bsd is to small to fill the partition, root only contain basics text
files to small to fill the partition.

It arrived when I was bulding cabal in ports. Any idea on where it fill
the partition ?


Bye
