-Some other packages must be installed for the above to work.  At a minimum, you need a standard UNIX shell, with standard UNIX tools like sed and GCC (or an alternate C compiler) in your execution path; MLton, the whole-program optimizing compiler for Standard ML; and the development files for the OpenSSL C library.  As of this writing, in the ``testing'' version of Debian Linux, this command will install the more uncommon of these dependencies:
+Some other packages must be installed for the above to work.  At a minimum, you need a standard UNIX shell, with standard UNIX tools like sed and GCC (or an alternate C compiler) in your execution path; MLton, the whole-program optimizing compiler for Standard ML; and the development files for the OpenSSL C library and the ICU C library.  As of this writing, in the ``testing'' version of Debian Linux, this command will install the more uncommon of these dependencies:
 \begin{verbatim}
-apt-get install mlton libssl-dev
+apt-get install mlton libssl-dev libicu-dev
 \end{verbatim}
 
 Note that, like the Ur/Web compiler, MLton is a whole-program optimizing compiler, so it frequently requires much more memory than old-fashioned compilers do.  Expect building Ur/Web with MLton to require not much less than a gigabyte of RAM.  If a \texttt{mlton} invocation ends suspiciously, the most likely explanation is that it has exhausted available memory.
