Hi there, I am trying to install cutadapt (package_cutadapt_1_8, from iuc) on a newly installed 17.05 Galaxy on Ubuntu. Both cutadapt and cython (a dependency) fail with the following errors: cutadapt/_align.c:8:22: fatal error: pyconfig.h: No such file or directory compilation terminated. error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 Cython/Plex/Scanners.c:8:22: fatal error: pyconfig.h: No such file or directory compilation terminated. error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 It seems that the python-dev package is missing. Should Galaxy have installed that (through the virtual environment) or does it need to be installed separately on the command line. If so, where would it have to go? Thanks for any help. Fiona
