missing / / in run_indep_wkflow_with_gnu_par.pl

Got this error: 
cat: out_NWcombine/list_args_for_final_step: No such file or directory
ls: cannot access out_NW/_/union_calls/_vcf: No such file or directory
/home/henk/vcftoolsperl/vcf-merge  out_NW/_/union_calls/_vcf.gz > out_NWEnt_NW.combined.vcf
sh: 1: /home/henk/vcftoolsperl/vcf-merge: not found

Errors are due to missing /'s in paths: should be easy fix.
