[SOLVED]need to install old library alongside current one

I have an issue with the icu package. Current one is 78.1. I write code with R language, and one package, named stringr, need icu 76. When opening my R shell, i have an error which prevents me to go further without errors. The output of this issue is:

  error: package or namespace load failed for ‘stringr’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/usr/lib/R/library/stringi/libs/stringi.so':
  libicuuc.so.76: cannot open shared object file: No such file or directory
--------------------
ls -al /usr/lib/R/library/stringi/libs/stringi.so
-rwxr-xr-x 1 gabx gabx 5.8M Feb 27  2025 /usr/lib/R/library/stringi/libs/stringi.so*

Is there any clean way to solve this issue, like installing somewhere (maybe in the R library path /usr/lib/R/library/stringi/libs the icu 76 arch package?

Thank you for help.

Rebuild that library against the new icu.

Thank you for your quick answer, but may you please explain me how to do that?

The same way you built/installed it in the first place.

Well, i don't see what you mean. I install R package from inside R, with

install.packages('stringr')

function. As for arch, i use pacman.
So I don't understand your answer, sorry.
Downgrading the icu package will break too many arch packages

You are aware that there is an stringr in aur ?
