Thank you for pointing this out. I confirmed that you are absolutely correct:

$ apt-cache pkgnames |grep ^pari | xargs -n1 sudo apt build-dep -y
$ git clone https://pari.math.u-bordeaux.fr/git/pari.git
pari.math.u-bordeaux.fr/git/pari.git
$ cd pari.math.u-bordeaux.fr/git/pari.git
$ sudo apt install bison
$ ./Configure
$ make -j 44 all
$ sudo make install
$ ln -sfr misc/gprc.dft $HOME/.gprc

$ find -type f -name 'pari.desc'
./src/desc/pari.desc
$ find  -type f -name '822.pm'
./src/desc/PARI/822.pm

Best,
Zhao
