 \subsubsection{Compiling Asterisk}
 
-To use the system c-client library, configure Asterisk with
-./configure --with-imap=system. If you downloaded the c-client source
-and compiled it according to the above instructions, configure
-Asterisk with with ./configure --with-imap=/usr/src/imap or where ever
-you built the UWashington IMAP Toolkit. When you run 'make
-menuselect', choose 'Voicemail Build Options' and the IMAP\_STORAGE
-option should be available for selection.
+Configure with ./configure --with-imap=/usr/src/imap
+or where ever you built thfe UWashington IMAP Toolkit. 
+
+A second configure option is to not specify a directory (i.e.
+./configure --with-imap). This will assume that you have the
+imap-2004g source installed in the .. directory relative to the
+Asterisk source.
+
+A third option is ./configure --with-imap=system. This will assume
+that you have installed a dynamically linked version of the c-client
+library (most likely via a package provided by your distro). This will
+attempt to link agains -lc-client and will search for c-client headers
+in your include path starting with the imap directory, and upon failure,
+in the c-client directory.
+
+Note that if you attempt one of the first two configuration options for
+IMAP and it fails, the "system" option will be automatically attempted.
+
+When you run 'make menuselect', choose 'Voicemail Build Options' and the
+IMAP\_STORAGE option should be available for selection.
 
 After selecting the IMAP\_STORAGE option, use the 'x' key to exit
 menuselect and save your changes, and the build/install Asterisk
