Hi Nelson,

or even better, configure using '--without-iconv'

Agreed.  Unfortunately even disabling iconv for all `native TeX Live' builds
would be overkill, because on many systems iconv is part of the standard
libc with no separate libiconv, e.g., on our Linux systems.  It would
certainly serve no useful purpose to disable iconv on such systems.

For native TeX Live builds they should check for dependencies on shared
libraries in general, not only those in /usr/local.
