+If you want to build things outside homebrew which depend on vips,
+such as ruby-vips, your pkg-config will need to be working. You
+need to point pkg-config at the homebrew area, and, additionally, at
+homebrew's libxml2 area:
+
+In your .profile, add something like:
+
+```bash
+export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/opt/libxml2/lib/pkgconfig
+```

+To verify that your vips install is correct and working, try:

+```bash
+$ vips --version
+vips-7.32.1-Mon May 20 10:01:38 BST 2013

+To verrify that your pkg-config is working correctly with vips, try:
