Haven't been able to build it yet, because my laptop runs out of memory,
but it might be enough to fix this.

Merely defining BOOST_TIMER_ENABLE_DEPRECATED=TRUE is not enough to make
it build with the current version of Boost.  I tried this before:

--8<---------------cut here---------------start------------->8---
+      '(modify-phases %standard-phases
+         (add-after 'unpack 'patch-build-system
+           (lambda _
+             (substitute* "CMakeLists.txt"
+               (("if\\(IMP_STATIC\\)" m)
+                (string-append "add_definitions(-DBOOST_TIMER_ENABLE_DEPRECATED=TRUE)\n" m))))))))
--8<---------------cut here---------------end--------------->8---
