Description:
Monotone is a distributed source management system that requires Botan to work. However, it seems that a greater version of Botan than 1.8 will break monotone. Note that this is not expressed in monotone's INSTALL notes but in its build system. See additional info.

Additional info:
* package version(s): botan-1.9.3-1 monotone-0.45-2
* See attached console log
* http://www.monotone.ca/INSTALL
* Exerpt from http://mtn-host.prjek.net/viewmtn/monotone/revision/file/c3badef3ef7b5f709b0fdb2a54855e0e3b265715/mtn_cvs/mtn_cvs.cc :
#elif BOTAN_VERSION_CODE <= BOTAN_VERSION_CODE_FOR(1,7,22)
E(linked_botan_version > BOTAN_VERSION_CODE_FOR(1,7,6), origin::system,
F("This monotone binary requires Botan 1.7.7 or newer."));
// While compiling against 1.7.22 or newer is recommended, because
// it enables new features of Botan, the monotone binary compiled
// against Botan 1.7.21 and before should still work with newer Botan
// versions, including all of the stable branch 1.8.x.
E(linked_botan_version < BOTAN_VERSION_CODE_FOR(1,9,0), origin::system,
F("This monotone binary does not work with Botan 1.9.x."));
#else
E(linked_botan_version > BOTAN_VERSION_CODE_FOR(1,7,22), origin::system,

F("This monotone binary does not work with Botan 1.9.x."));
#endif


Steps to reproduce:
pacman -S monotone && /usr/bin/mtn

Expected output:
[...]
mtn: error: This monotone binary does not work with Botan 1.9.x.
