My environment is Debian on aarch64, with Guix as the package manager.
So it is possible that the Debian environment disturbs what is happening;
but I see the problem depending on whether I install the new or the old
libgcrypt from Guix.

Here are lines from config.log with things related to crypto in them:
configure:8987: checking whether Guile-Gcrypt is available and recent enough
configure:9005: result: yes
...
configure:9062: WARNING: The Guile-Lib requirement was not satisfied (>= 0.2.7);

configure:10941: result: yes
configure:10950: error: GNU libgcrypt not found; please install it.

So this is not related to libgcrypt, but to libgpg-error.so linked with an old
glibc; we should be at 2.35 in core-updates, no?

Strangely enough, when I do ldd on /home/andreas/.guix-profile/lib/libgpg-error.so.0
then it is linked with /gnu/store/...-glibc-2.35/lib/libc.so.

Where does this pthread_mutex_trylock <at> GLIBC_2.34 come from?

I tried "guix shell --pure -D guix" and then "./configure", but the result
is the same.

I will try again on my pure Guix machine.

Andreas
