 ## Installation
@@ -20,10 +20,16 @@ Clone and install from source:
 
     git clone https://git.etenil.net/downstroke
     cd downstroke
-    chicken-install
+    chicken-install -s
 
 This will install the `downstroke` egg and all its dependencies. Ensure you have the required system libraries installed first (see [Dependencies](#dependencies) below).
 
+Note: On modern systems, installing `expat` can result in incompatible pointer errors. A way around this is to invoke `chicken-install` like so:
+
+```
+CFLAGS="-Wno-incompatible-pointer-types" chicken-install -s
+```
