Rosetta 3.3 installation error

Hi,

I am trying to install rosetta 3.3 on fedora core 14 platform. I am getting the following error after executing scons bin mode=release command :-

[pauling@BME rosetta_source]$ scons bin mode=release
scons: Reading SConscript files ...

Could you tell me how to rectify this error ??
