+      <listitem>
+	<para>Linking a small program should take no more than a few
+	seconds.  Larger programs can take longer, but even linking
+	GHC itself only takes 3-4 seconds on our development
+	machines.</para>
+	
+	<para>Long link times have been attributed to using Sun's
+	linker on Solaris, as compared to GNU <command>ld</command>
+	which appears to be much faster.  So if you're on a Sun box,
+	try switching to GNU <command>ld</command>.  <ulink
