hphp: /home/ubuntu/Desktop/dev/hiphop-php/src/compiler/analysis/variable_table.cpp:818: void HPHP::VariableTable::checkSystemGVOrder(HPHP::SymbolSet&, unsigned int): Assertion `false' failed.
Core dumped: Aborted
hphp failed
running hphp took 0'12" (12662 ms) wall time

Reason:

This error occurs when the path for HPHP compiler is not set or incorrect path were set.

Solution:
To get the rid of it, run the following command under "hiphop" base directory not from other directory.

$:~/Desktop/dev/hiphop-php# export CMAKE_PREFIX_PATH=`/bin/pwd`/../
$:~/Desktop/dev/hiphop-php# export HPHP_HOME=`/bin/pwd`
$:~/Desktop/dev/hiphop-php# export HPHP_LIB=`/bin/pwd`/bin

or else set the exact path in /etc/environment file if you know.

Note : This is tested under Ubuntu 11.10.
