[racket] Failed to build Racket Textual 5.1.2 (CentOS)

Hello,

Just as a follow-up, I'm trying to install Racket on a lab's computer
running "Red Hat Enterprise Linux 5.7", gcc (GCC) 4.1.2 20080704 (Red Hat
4.1.2-51).

Racket 5.1.3 unix source still shouts the same error message when trying to
compile without workarounds...
At least now I know what to do :)
