I am porting STAF based perl services to new perl version. When trying to load threads in thread modules, getting error

threads.so: undefined symbol: PL_thr_key at /opt/ActivePerl-5.26/lib/XSLoader.pm

I saw some post which says this occurs if perl is not threaded. However, I have installed threaded perl downloaded from Active State. version is perl 5.26.1

Any clue to solve this?
