The --enable-hl configure flag enables high level library support, for libraries such as netcdf4-python. Please could you include this in the hdf5 builds?
The high level library is enabled by default and so --enable-hl does not need to be specified. What problems are you running into? Are you working on a netcdf4-python package?
My apologies - having looked through the spec files and not having seen --enable-hl, I thought that was the problem I was having. It turns out I was having a problem with the netcdf4 package in F10.
I don't have any particular plans to package netcdf4-python because it needs netcdf4.0.1 to build and I'm still using F10 which has 4.0.0.
