-    <p>HP/UX has a documented characteristic where the shl_unload() function
-    always unloads a library, regardless of how many times the library has
-    been loaded. Most operating systems reference count libraries as they are
-    opened. In the future (Jitterbug 414) this may be corrected in ICU, but
-    at present, we work around this problem by simply NOT ever unloading
-    shared libraries. This means that once a data library is loaded (ex:
-    libicudata.sl) by a process, it cannot be unloaded and replaced without
-    stopping and restarting the process.</p>
+    <p>If you are building on a Unix platform, it is important that you add
+    the location of your ICU libraries (including the data library) to your
+    LD_LIBRARY_PATH environment variable. The ICU libraries may not link or
+    load properly without doing this.</p>
