I get this error:

configure:5233: gcc -o conftest -g -O2 -finput-charset=ISO-8859-1 
-fexec-charset

cc1: error: no iconv implementation, cannot convert from ISO-8859-1 to UTF-8
conftest.c:75:54: error: no iconv implementation, cannot convert from 
ISO-8859-1
 to UTF-8

I have iconv installed though, so I don't undersand what's going on. 
perhaps it is missing a certain kind of conversion? Also, I have iconv 
installed as an extra package, while gcc is part of the base system, so 
depending on an extra package is somehow strange (and it doesn't even work).
