+Standard configure flags should work.  In particular, see:
+
+   --disable-shared          Only build static libraries
+   --prefix                  Install all files relative to this directory.
+
+
+The configure script also supports the following flags:
+
+   --enable-gcc-warnings     Enable extra compiler checking with GCC.
+   --disable-malloc-replacement
+                             Don't let applications replace our memory
+                             management functions
+   --disable-openssl         Disable support for OpenSSL encryption.
+   --disable-thread-support  Don't support multithreaded environments.
