Yes. Well, just started to dive into R and that's probably the problem (like in old UNIX times), the help aka man pages are very useful and sufficient, if you know the language/system ... ;-)

Ah - ok, haven't applied the latest release.diff. But anyway, for a newbie it is not easy to find out, what "meta" is expected to be.

Yepp - with a leading uppercase E it works. Thanx a lot!!! :)

OT: Wondering, what does "recommended portable encoding names" in this context mean (e.g. AFAIK 'latin1' is not a standardized name ...).

BTW: Just build R-2.10.1 on Solaris Nevada b129 (x86_64) using its native iconv facilities in libc and sunperf libs (wrt. BLAS/LAPACK) only. It works now and all checks are saying, everything is ok.

Ahh - good hint - help("check") wasn't really fruitful. However,

elkner.idev2 build/R-2.10.1/bin > ./check --help Can't locate File/Copy/Recursive.pm in @INC (@INC contains: ...

So still need to do a little bit tweaking ...

Anyway, thanx a lot for your quick help!!!, jel.
