When trying to compile libctl from source (069e736) with the flag --without-guile, I run into this error:
$ ./configure --without-guile
$ make
Making all in utils
make[2]: Entering directory '/home/oskooi/install/libctl/utils'
make[2]: *** No rule to make target 'geom-ctl-io.c', needed by 'all'. Stop.
Inspecting config.log, I find these lines which seems should not be there:
config.status:1169: creating utils/gen-ctl-io
GEN_CTL_IO='/home/oskooi/install/libctl/utils/gen-ctl-io'
