This is my first post here, so please be patient with me.
I am trying to build qwt-6.0.2 against qt-4.8.0 on RedHat Enterprise Linux 6 64bit computer. The build fails with many errors and here is the beginning of it:

zms@ilc-esb09 $ qmake
zms@ilc-esb09 $ make
cd src/ && make -f Makefile
make[1]: Entering directory `/opt/qt/qwt-6.0.2/src'

I have successfully build qwt-6.0.2 against qt-4.7.0 on rhel5 32bit Linux.
The build output is entirely different in this successful case, where I do not see the g++ command, instead
compiling <some file.cpp>
is printed for each file that is being compiled. Could be that something is not right with my qt installation?

I appreciate any suggestions as to what I need to do to correct this problem.
Thanks,
