can you post the output of /etc/redhat-release?
I guess your CentOS version is similar to 7.xx5xx which triggers Centos 5.x build process.
You can get rid of lines 10 to 26 and 60 to 65. Also remove $(RHEL5_SETUP) from line 44.

No need to do that @rezass

As you know somewhere in the makefile is a grep 5.[0-9]. This can be easily solved by replacing it with grep 5[.][0-9].

As a prrgrammer i had same thoughts while looking through mkefile code) But i do not know C.

May be key "--force" will help but in future it may be cause of weird errors.

@StCremer установил нет?
