+`HEAD` as it's basically the only source that is managed in a way to ensure

+### Building from sources on MacOSX
+
+When using [brew](https://brew.sh), it should be a simple `brew install
+--head pgloader`.
+
+When using [macports](https://www.macports.org), then we have a situation to
+deal with with shared objects pgloader depends on, as reported in issue #161
+at <https://github.com/dimitri/pgloader/issues/161#issuecomment-201162647>:
+
+> I was able to get a clean build without having to disable compression after
+> symlinking /usr/local/lib to /opt/local/lib. Note that I did not have
+> anything installed to /usr/local/lib so I didn't lose anything here.
+
+### Building from sources on Windows
+
+Building pgloader on Windows is supported, thanks to Common Lisp
+implementations being available on that platform, and to the Common Lisp
+Standard for making it easy to write actually portable code.
+
+It is recommended to have a look at the issues labelled with *Windows
+support* if you run into trouble when building
+pgloader:
