<para><userinput>--with-shared:</userinput> This enables the build of the
shared ncurses library files.</para>

<para><userinput>--disable-termcap:</userinput> Disabled the compilation of
termcap fall back support.</para>

<para><userinput>cd /lib &amp;&amp; mv *.a /usr/lib :</userinput> This
moves all of the static ncurses library files from /lib to /usr/lib.
/lib should only contain the shared files which are essential to the
system when /usr may not be mounted.</para>

<para><userinput>chmod 755 *.5.2:</userinput> Shared libraries should be
executable.  Ncurses install routine doesn't set the permissions
properly so we do it manaully instead.</para>

<para><userinput>ln -sf libncurses.a libcurses.a:</userinput> Some
programs try to link using -lcurses instead of -lncurses.  This symlink
ensures that such programs will link without errors.</para>

<para><userinput>ln -sf ../../lib/libncurses.so etc:</userinput> These
links are created because if they aren't, the linker will not find the 
dynamic libraries when linking and so link all programs with the static
versions.</para>
