This is covered in the 'R Installation and Administration' manual that
INSTALL asked you to read.  Specifically for Solaris:

 Modern Solaris systems allow a large selection of Open Source software
 to be installed via @command{pkg-get}: a Sparc Solaris 10 system came
 with @code{libreadline} and @code{libiconv} and a choice of @code{gcc3}
 and @code{gcc4} compilers, installed under @file{/opt/csw}.  (You will
 need GNU @code{libiconv}: the Solaris version of @code{iconv} is not
 sufficiently powerful.)

R 2.7.0 is documented to build on several versions of Solaris in that manual, so the problem is definitely not 'R on Solaris'.

You analysis is plain wrong. Search for r_cv_iconv_latin1 in configure and you will see three lines which set it (plus one that checks if it was set in the cache).


Thanks a lot. Clearly when I compiled R directly, it see my GNU libiconv rather than the Sun supplied one, but when built as part of Sage, it see the Sun one. That should be easy to fix.
