every time in exactly the same place.

this location of "../../../../../config_h.SH is the same as /home/config_h.SH - /home/admtst is a bind mount on /opt/home/admtst

so I presume the problem is here but have no idea why

    Problem solved YAY!!!!!!!

    it was a problem when it got to /home which does not properly exist - I do not know how these bind mounts work on an OS level so cant explain exactly the reason for the issue...

    However, changing cpanm build directory to another location which is done using an env variable: 

    export PERL_CPANM_HOME=/opt/app/.cpanm

    So issue closed for me!
