4.3.1 compile fail: libiconv

Hi everyone, I'm trying compile install php 4.3.1 on a RedHat 6.2 system. Whenever I try to add support for flash or xslt, it dies with libiconv errors (see below.) I've removed older versions of libiconv and installed the newest version, 1.9.1. Does anyone have any suggestions or ideas? Below is my configure line. Any help is greatly appreciated.
