Configuring Psi ...
Verifying Qt 3.x Multithreaded (MT) build environment ... fail

There was an error compiling 'conf'.  Be sure you have a proper
Qt 3.x Multithreaded (MT) build environment set up.  This
means not just Qt, but also a C++ compiler, the 'make' command,
and any other packages necessary to compile C++ programs.
See conf.log for details.
