Checking out the repositories icarusalg, icaruscode and larcorealg (with or without larcore) has MRB set icarusalg as the first repository to CMake.
The correct order would be larcorealg, larcore, icarusalg and icaruscode.

Steps to reproduce:

pwd
source /cvmfs/icarus.opensciencegrid.org/products/icarus/setup_icarus.sh
mrb newDev -v v09_33_00 -q e20:prof
source /icarus/app/users/petrillo/LArSoft/tests/pkgOrder/localProducts_larsoft_v09_33_00_e20_prof/setup
mrb gitCheckout --tag LARSOFT_SUITE_v09_33_00 larcorealg
mrb gitCheckout --tag LARSOFT_SUITE_v09_33_00 larcore
mrb gitCheckout --tag v09_33_00 icarusalg
mrb gitCheckout --tag v09_33_00 icaruscode
mrbsetenv
mrb build -C

Manually fixing the order in ${MRB_SOURCE}/CMakeLists.txt fixes it (until the next mrbsetenv).
