I am just blathering here without actually testing, but my
guess is the following.

The normal cause of this problem is the fact that on Solaris libraries
must be linked with

  -L libdir -lname -R libdir -lname

It is the -R argument that tells the compiled binary to search for the
library in that location at runtime.

This can be corrected by using the $LD_RUN_PATH and/or $LD_LIBRARY_PATH
environment variables, but that is a bad idea.  (Never set these unless
someone else already broke some packages in this way.  I always unset
them explicitly before I compile anything.)
It's better to make sure the (right) -R is used at compile time.

A lot of software fails to insert the -R.  As a result, it can't find the
library at runtime.  A couple of packages installed on www.freeciv.org,
which runs Solaris, have this problem.  GTK+ also has this problem:
after installing it you manually have top insert the -R argument into
the glib-config and gtk-config scripts.

Of course the Freeciv ./configure phase should insert all the -Rs
automatically, and I thought it already did.  I compile Freeciv
on Solaris without this problem.

libiconv is a character set handling library, and it is not required
by Freeciv directly, as far as I know; however, Freeciv requires
GNU gettext (unless --disable-nls is used), and GNU gettext can
optionally be compiled with libiconv.  So my guess is that you have
to insert a -Ri /path/to/libiconv-1.x/lib -liconv to $LDFLAGS.
