[HOpenGL] Problems compiling with profiling enabled

Hello, when I try to compile a program that uses HOpenGL with profiling enabled, GHC complains about types not being declared and functions not being exported (all names belonging to the HOpenGL package). Does HOpenGL lack profiling support or am I doing something wrong ? How would I go about installing the package so that profiling works ? Thank you for your help. Yann Morvan
