 === '''Use ccache outside MacPorts''' ===
 
-To use ccache also outside MacPorts you have to edit your PATH which is set in your `.profile` or `.bash_profile`.
+MacPorts doesn't create symlinks to local compiler therefore you need to create it manually.
+
+One way could be to use the following script that find the available compilers and create symlinks on {{{/opt/local/libexec/ccache}}}.
+
+{{{
+#!/bin/sh
+
+##
+## run with sudo or adjust prefix/dest_links
+##
+
+# adjust if needed
+prefix="/opt/local"
+dest_links="${prefix}/libexec/ccache"
+bin_paths="/usr/bin /opt/local/bin /usr/local/bin"
+ccache_bin=$(which ccache)
+
+# set umask to avoid strict starting shell
+umask 022
+
+if [ ! -d ${dest_links} ]; then
+  install -d ${dest_links}
+fi
+
+find $bin_paths \( -name "gcc*" -or -name "cc*" \
+  -or -name "g++*" -or -name "c++*" \
+  -or -name "clang++-mp*" -or -name "clang-mp*" \) | \
+  egrep -v "cmake*|ccache*|ccomps*|c\+\+filt*" | \
+while read file; do
+  base=$(basename $file)
+  ln -s ${ccache_bin} ${dest_links}/${base}
+done
+
+echo ">> add $dest_links in front of your \$PATH"
+}}}
+
+
+Now to use ccache also outside MacPorts you have to edit your PATH which is set in your `.profile` or `.bash_profile`.
 
 First, locate the file you are using. If there is a `.bash_profile` edit this file, if there is only `.profile` you want to edit this.
