Error while installing UVFS on Centos 2.6

System

Has anyone ran into this:
Getting an error while trying to compile UVFS:

[root@AnsslerLab uvfs_2.0.3]# gmake
/usr/bin/gcc -g -O3 -Wall -I. -c -o uvfs_signal.o uvfs_signal.cc
/usr/bin/gcc -g -O3 -Wall -I. -o uvfs_signal uvfs_signal.o -lpthread -lc -lstdc++ -lm
gmake -C /lib/modules/2.6.32-71.29.1.el6.x86_64/build SUBDIRS=/opt/uvfs/uvfs_2.0.3 modules
gmake[1]: Entering directory `/usr/src/kernels/2.6.32-71.29.1.el6.x86_64'
scripts/Makefile.build:49: *** CFLAGS was changed in "/opt/uvfs/uvfs_2.0.3/Makefile". Fix it to use EXTRA_CFLAGS. Stop.
gmake[1]: *** [_module_/opt/uvfs/uvfs_2.0.3] Error 2
gmake[1]: Leaving directory `/usr/src/kernels/2.6.32-71.29.1.el6.x86_64'

I've tried changing makefile to use EXTRA_CFLAGS also, but no luck.

Thanks
