1/ as pointed out in issue 2, the dependency packages are not automatically installed.
2/ the installation aborted because GTK+ was not installed. I installed it using the link that was proposed in the error message http://r.research.att.com/libs/GTK_2.24.17-X11.pkg
3/ GTK+ does not seem to work as a stand alone on Mac OS. When I retried to install explora, I got a message telling me to update X11 which is a window system (X.Org) . I tried installing this package but was told that this update requires Mac OS 10.7
It actually seems that X11 is no longer supported by apple (http://support.apple.com/kb/HT5293) and that the project now relies on an open-source project XQuartz http://xquartz.macosforge.org/landing/. After installing XQuartz-2.7.7, the installation of Explora aborted all the same, with the following message
install.packages("~/Downloads/explora.tar.gz", repos = NULL, type = "source")
