- Even-though I have set the required executable like ld,ar,make,zip in $PATH.
I was continuously getting this error.

- Verified the $LD_LIBRARY_PATH (all correct)

- Verified $PERL5LIB correctly set.

Issue
======

When I checked the disk space I came to know that the /tmp was full and there was no free space.

On deleting old and unwanted files I reclaimed some space in /tmp.

After clearing files in /tmp on invoking adcfgclone.pl it was successful and clone completed without any issues.
