Since you are generating and running the Perl script from inside the C program, the problem is likely in how you are running Perl from the C program. It is quite possible that environment is wrong. Check the PATH and PERL5LIB. Check which Perl is being used. It is possible that there is an old perl version installed which is getting run instead of the one you expect.

Why can't you pull the Perl code out of the C program? Put the Perl code in its own file. Then have the C program call the script with the arguments it needs. Much simpler, and you can debug or use the Perl script outside of the C program.
