Hi,
thanks for all your suggestions so far.
I also guess, that the WPI tool only cares for other WPI installations, but not for RPM packages.
There are some Perl RPMs on my system, the one named "Perl" is on version 5.16.1-9.
Dave's suggestion to install Paul's Perl 5.8.8 WPI package was my first idea but it is not available (for me) anywhere.
So there seems no other way as to inspect the WPI package in its details, as Lars already suggested in the German OS/2 forum.
I'm not familiar with this and I will try to follow Steven's advice. This will take some time and whenever I succeed I will report it here.

I downloaded
https://exiftool.org/Image-ExifTool-13.27.tar.gz, it doesn't even need installed. You should install some other Perl packages, see the README, then open ANPM, go to the available packages, scroll down to perl and you should be able to guess which packages supply stuff, eg the 1st 2 requirements,
Archive::Zip (ZIP, DOCX, PPTX, XLSX, ODP, ODS, ODT, EIP, iWork)
Compress::Zlib (DNG, PNG, PDF, DCM, MIE and SWF files)
are covered by
perl-Archive-extract
perl-Archive-Tar
perl-Archive-Zip
Tar might not be needed but doesn't hurt to add. Not all packages are available, some don't make sense for us such as the Win32 ones.
To run, just prefix the command with perl, after going to the folder you extracted the package to, eg the example,
perl ./exiftool t/images/ExifTool.jpg
Note using slashes instead of backslashes and the beginning ./ just means the current directory.
As Steve mentioned, it wouldn't be hard to examine the wic from ExifTool_Perl_9-46.wpi to figure out the program files. To access the wic, you need to run wic.exe -X ExifTool_Perl_9-46.wpi. wic.exe should be in C:\sys\install\WARPIN, or whatever drive letter you installed to.

https://exiftool.org/ for other cmd line options, just remember on OS/2 you need to prefix the command with perl or perl.exe
