FWIW, with 2.0.7+ on x86_64-linux-gnu, with GMP 5.1.0:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (use-modules (rnrs bytevectors))
scheme@(guile-user)> (define not-32-bit (expt 2 32))
scheme@(guile-user)> (define bv (make-bytevector 4))
scheme@(guile-user)> (bytevector-u32-set! bv 0 not-32-bit (endianness big))
<unnamed port>:4:0: In procedure #<procedure 1b1bf00 at <current input>:4:0 ()>:
<unnamed port>:4:0: In procedure bytevector-u32-set!: Value out of range: 4294967296

Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.
--8<---------------cut here---------------end--------------->8---

As Mark pointed out, it could be due to the GMP version you’re using.

Could you check that?

TIA,
Ludo’.
