That's what I suspect as well, but I don't know how to fix it just yet.
What appears to happen is this: I set a -L and -R path to the location
of GNU iconv in LDFLAGS, and -I in CFLAGS, but then libtool in it's
infinite wisdom decides that the autoconf test for iconv (which uses
iconv_open) does not require -liconv to link, so it removes the -L, -R,
and -I flags I set. This happens as part of the m4 build macros for
apr-util, namely the APR_REMOVEFROM macro.

For kicks, I defeated autoconf by removing these sections from
apu-iconf.m4. The problem still appears to be that apr-util's xlate.c
uses 'iconv_open', not libiconv_open. My last round of hacking did not
turn up any viable solution, and then other concerns (aka paid work)
caused me to put looking for a fix on hold. I have access to lots of
Solaris boxes with SunONE compiler suite installed, so if anyone has
suggestions on how to fix this, let me know and I'll give it a shot!

Regards,
Cory.
