Thanks, here is the result:

$ guix package -p profile-A -I
glibc   2.31    out /gnu/store/ksy2b6fwfmz40gjajvspl87ia4vsfzj7-glibc-2.31
gcc-toolchain   4.9.4   out 
/gnu/store/frmwyxb8zl8vwd7840gb7j526c4dzxh0-gcc-toolchain-4.9.4
make    4.3     out /gnu/store/4k33n2nhsnnaxk2ip75gj7xiqdjns5hq-make-4.3
cmake   3.19.2  out /gnu/store/4axd987cf0bpkshybl1w7g5hp9yqm660-cmake-3.19.2
zlib    1.2.11  out /gnu/store/rykm237xkmq7rl1p0nwass01p090p88x-zlib-1.2.11
icu4c   68.2    out /gnu/store/hjggah4g7vb4db3c62lmmpqplv5g4drh-icu4c-68.2
pcre    8.44    out /gnu/store/k0aqiy7yx8n28dvm3f0a04ka5sd8y950-pcre-8.44
gsl     2.6     out /gnu/store/xq64iaxx2gmlcgnipj31wjxlf1yd2g2p-gsl-2.6

But glibc is 2.31 instead of 2.33

Thank you, yes packages installed are always evolving. I will now 
promote to use manifests.
