You seem to rely on perl5.8.7 to be found via $ENV{PATH} - I would want to eliminate any such reliance by using an explicit exec /opt/perl/bin/perl5.8.7, so that both users will always invoke exactly the same Perl binary. As BerkeleyDB uses a binary component, that component must be tailored to the perl5.8.7 you use. If for example one Perl was compiled with threads and the other wasn't, that might lead to the problems.

Also, could you elaborate on how the runme.sh "fails" ? Is there any error output given?
