The ndbm part of the gdbm library got moved into gdbm_compat.
This requires perl to be linked against the gdbm_compat
library, without it numerous other programs cease to work.
This has been in the perl RT complete with a fix, for months
now:
RT #24444
and elsewhere:
gentoo 32510
What does it take to catch the attention of someone who can
take action on this upstream?
