 Using directory paths with spaces is not supported at this time: you
 must re-configure without using spaces.
 
+*** On Solaris, use GNU Make when installing an out-of-tree build
+
+The Emacs configuration process allows you to configure the
+build environment so that you can build emacs in a directory
+outside of the distribution tree.  When installing Emacs from an
+out-of-tree build directory on Solaris, you may need to use GNU
+make.  The make programs bundled with Solaris support the VPATH
+macro but use it differently from the way the VPATH macro is
+used by GNU make.  The differences will cause the "make install"
+step to fail, leaving you with an incomplete emacs
+installation.  GNU make is available in /usr/sfw/bin on Solaris
+10 and can be installed as /opt/sfw/bin/gmake from the Solaris 9
+Software Companion CDROM.
+
+The problems due to the VPATH processing differences affect only
+out of tree builds so, if you are on a Solaris installation
+without GNU make, you can install Emacs completely by installing
+from a build environment using the original emacs distribution tree.
