# conan-center-index's lzo/2.10 recipe fetches straight from
# oberhumer.com's own tiny personal mirror at conan-install time, which
# routinely answers real, fully-connected HTTP requests with a bare
# "501 Not Implemented" (reproduced directly with the same request Conan
# makes; not a DNS/connectivity problem, the one-person server itself is
# just unreliable). Conan's "sources backup cache" feature lets us hand it
# this file locally, keyed by the sha256 its own conandata.yml already
# expects, which skips that flaky request entirely -- see src_unpack/
# src_configure. Pinned to lzo/2.10's one known conandata.yml entry.

# in the tarball. This needs network access during src_configure/src_compile,
# which Portage blocks by default under FEATURES=network-sandbox.
