I tried to install HHVM on Mac OS X Yosemite, but it failed and at last I can not make any installation MacPort.
For example, if I try to install pear , with this command line:
sudo port install php55-pear
Result :

sudo port -v selfupdate port upgrade outdated sudo port upgrade outdated sudo port search ImageMagick sudo port install ImageMagick port selfupdate sudo port selfupdateAn important detail , MacPorts went from version 2.3.3 to version 2.3.4 in this update .
