make errors

I am trying to make scilab-branches-5.1-1244468876 on
Centos 5. After installing all the dependencies I ran
make and received the following errors:

make[3]: Leaving directory
`/usr/local/scilab/scilab-branches-5.1-1244468876/modules/output_stream'
make[2]: Leaving directory

Can someone help with this problem?

Thanks,
