# see http://pyyaml.org/wiki/LibYAML for libyaml upstream docs

# our hacking of upstream is noticed during build:
#  * installing *source* package ‘yaml’ ...
#  files ‘src/api.c’, ‘src/dumper.c’, ‘src/emitter.c’, ‘src/loader.c’, ‘src/parser.c’, ‘src/reader.c’, ‘src/scanner.c’, ‘src/writer.c’, ‘src/yaml.h’ are missing
#  files ‘src/Makevars’, ‘src/implicit.c’, ‘src/r-ext.h’ have the wrong MD5 checksums
# FIXME: get rid of these warnings

# we need -lyaml , if this lacks we get:
#      ** testing if installed package can be loaded
#      Error in dyn.load(file, DLLpath = DLLpath, ...) :·
#        unable to load shared object '.../r-cran-yaml-2.1.13/
#        debian/r-cran-yaml/usr/lib/R/site-library/yaml/libs/yaml.so':
#        .../r-cran-yaml-2.1.13/debian/r-cran-yaml/usr/lib/R/
#        site-library/yaml/libs/yaml.so: undefined symbol:
#        yaml_sequence_start_event_initialize
#     Error: loading failed
# during build

# FIXME contact upstream, do stress-test our yaml.so; perhaps we'd better ship a
#  src/Makefile: this could be useable by both us and upstream.
