In the 3.6.5-0.3 builds, the various logs are put under /opt/rh/devtoolset-1.1/root/usr/var/log/pcp/*/*.log. Note the extraneous /usr.
Since pcp-3.6.6 will have the autoconf/prefix rework included, is this bug worth investigating at this stage? (given any 3.6.5 fix is certain not to be applicable for 3.6.6, which is just around the corner). Or is the -0.3 extension indicating a patched pcp-3.6.5, with --prefix rework patched in? Using http://brewweb.devel.redhat.com pointer from late yesterday, I'm not finding the -0.3 build.
According to /etc/rpm/macros.scl from scl-utils-build-20120423-2.el6: %global _prefix %{_scl_root}/usr %global _localstatedir %{_prefix}/var _localstatedir should actually just be %{_scl_root}/var; compare /usr/lib/rpm/redhat/macros. There might be other mismatches.
This is fixed in latest version of scl-utils that will be part of DTS 1.1. Closing the bug.
