(The above shows that this is Perl as built by Guix, not Nixpkgs.)

Wild guess: you’re building outside of a chroot, and Perl’s configure
found /usr/lib/libgdbm.so, so it decided to link against it, which
didn’t work because our linker doesn’t look for libraries there.

Can you confirm?

Solution: add “build-use-chroot = true” in nix.conf.
