It points to a binary that does not run on its own.
bash-4.1$ ./lib/mono/4.5/mcs.exe --version
bash: ./lib/mono/4.5/mcs.exe: cannot execute binary file
but, if I run it with mono it will work.
bash-4.1$ bin/mono ./lib/mono/4.5/mcs.exe --version
Mono C# compiler version 3.2.7.0
Prior to the change, it was the mcs wrapper that was being executed, after
the change, it is trying to run the .NET binary directly. The contents of
mcs is:
#!/bin/sh
exec /opt/local/JenkinsBuilds/bin/mono $MONO_OPTIONS
/opt/local/JenkinsBuilds/lib/mono/4.5/mcs.exe "$@"
