When I invoke 'grads' in terminal, I got following error.

grads: symbol lookup error: /usr/lib/aarch64-linux-gnu/libgxdCairo.so: undefined
symbol: gxdbkq
-----

I used 'nm' to find "gxdbkq".
$ nm -D /usr/bin/grads

In my X86-64 Ubuntu PC, "gxdbkq" is found in '/usr/bin/grads' and
'/usr/lib/x86_64-linux-gnu/libgradspy.so'.

Unfortunately, I cannot find "gxdbkq" in 'grads' in my arm64 environment.
"gxdbkq" is only found in '/usr/lib/aarch64-linux-gnu/libgradspy.so'.
Furthermore, I cannot find any symbol names which comes from GrADS source
code (such like, gabarb, gabufr_open, gxdbkq, etc) in '/usr/bin/grads'
installed in arm64 environment.


I use Canonical's multipass environment on MacOS Monterey.
OS is Ubuntu 20.04 LTS with kernel 5.4.0-104-generic and libc6 2.31-0ubuntu9.7.
grads_2.2.1-2build3_arm64.deb were installed.
