Re: [igraph] igraph 5.2 does not load in R 2.9.0, causes DLL error

[Gábor Csárdi]

I think that rebuilding/reinstalling igraph should solve the problem.

My understanding is that there is only a problem if you load a package
with R 2.9.0, but the package was built on 2.8.1. Some CRAN mirrors
have igraph packages that were built with R 2.8.1, but they should
disappear soon. Use e.g. the Austrian mirror, that should be always
up-to-date.

I will also replace the R package on the igraph homepage with one that
was built with R 2.9.0.
