Please find attached ebuild for libdevmapper-1.00.18. This is needed for dm-crypt (see Bug #44347). I suggest to put in to dev-libs/libdevmapper. "The Device-mapper is a new component of the linux kernel that supports logical volume management. It is required by LVM2 and EVMS. The original LVM (included in stock 2.4 kernels) does not use it. If you intend to use Device-mapper, as well as adding it to your kernel, you should install the userspace configuration tool (dmsetup) and library (libdevmapper). The encryption target (dm-crypt) has its own web page at http://www.saout.de/misc/dm-crypt/." Reproducible: Always Steps to Reproduce: 1. 2. 3.
