Re: libsigc++ problem
We've got to the bottom of this problem, it's a problem in a broken autoconf version. I've distributed quick fixes for the configure script that should fix it. They can be found at:
I think I provide sufficient instructions within the README for which packages on different distributions - it is up to you to know where to get your distribution packages from.
If it's sources you're after, in the README it says:
> Sources for these libraries can be found on or linked from:
There is a link for libsigc++ clearly on the front page there.
Hope that helps,
