[racket] Amazon Linux update causes `require' in 5.1.1 to hang indefinitely?

I'm trying that now (first time ever).

Unfortunately the make is stuck at the last line for 10+ minutes, with
`top' showing xform.rkt pegged at 99% CPU.

Make output:

...

--setup . --cpp "gcc -E -I./.. -I../../../racket/gc2/../include
-pthread   -DNEWGC_BTC_ACCOUNT  -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 "  --keep-lines -o xsrc/precomp.h
../../../racket/gc2/precomp.c

Meanwhile `top' shows xform.rkt pegged at 99% CPU.

So seemingly the build of Racket involves running Racket, and is
encountering the original problem I had? Presumably xform.rkt has a
`require' early on?
