Can't locate RT.pm in @INC after 3.8.0 "upgrade", {} subdirs

I’ve “upgraded” from 3.6.6 (renamed dir to rt-3.6.6 and installed 3.8
with make upgrade) and also tried to add–enable-layout=RT3 to my
./configure but I still get the following when starting apache:

/opt/csw/apache/bin/apachectl startssl: httpd could not be started

There were no files in /opt/csw/rt3/lib except for a subdir called {} so
I moved the contents of that dir up to lib. It looks like there are
subdirs all over my RT install named {}, does anyone know how to fix
this on Solaris 10? Thanks,
