In the meantime I'll see if I can build a fresh set of static ft that will work with the current iconv - it's a bit convoluted as we need a build that won't use CF so Cairo can be forked (for multicore, Rserve etc.).

I would suggest you use the binary unless you really know what you're doing (obviously you can replicate the CRAN setup but apparently you chose not to).
