error building LALInference in conda

Hi,

on CIT with environment-py36.yml, I get the following error after running make in the LALInference directory:

  CC       liblalinference_la-LALInferenceHDF5.lo
LALInferenceHDF5.c: In function 'LALInferenceH5DatasetToVariablesArray':
LALInferenceHDF5.c:73:9: error: variable 'ret' set but not used [-Werror=unused-but-set-variable]
     int ret;
         ^~~

 }

config.log is attached. While the LALInference developers (hm...) should fix those errors, I wonder how come those did not appear in the automated conda builds for LALInference.
