[Halld-offline] problems compiling sim-recon with root6

[Nathan Sparks]

The simplest long term fix for the group is to remove CPLUS_INCLUDE_PATH from the rcdb env-setup script.

I removed it from hdpm a long time ago.
This is why I did not encounter this problem.

This worked ok. But then when I go to build sim-recon against this new root 6 I am getting consistent failures in hdview2. See below for the compiler errors. Anyone else seeing this? The error message seems to indicate we should be using quotes instead of angle <> in the #include string.
