Copied over to separate issue as per #6 (comment)
I'm not quite sure on your overall approach to bundle this as Gem. Somehow we'd need to download cgimap sources, compile them, all during cgimap-ruby compilation/installation. Otherwise, installing openstreetmap-cgimap PPA first, before installing cgimap-ruby seems to somehow defeat the purpose of having something easily installable. Then, there's the issue of keeping the new Gem in sync with cgimap sources.
In case your goal was to have one single cgimap.so
with no additional dependencies to other cgimap shared libs, a static build seems like the way to go. In this case additional shared libraries need to be included, like I mentioned in #5.
Static build (./configure --enable-static --disable-shared CXXFLAGS="-fPIC" --enable-yajl
) requires additional references to yajl and libmemcached:
abort "missing yajl" unless have_library('yajl', 'yajl_gen_alloc(NULL)', 'yajl/yajl_gen.h')
abort "missing memcached" unless have_library('memcached', 'memcache::Memcache m()', 'libmemcached/memcached.hpp')
When compiling with bundle exec rake compile
I get
conftest.c:3:42: fatal error: cgimap/backend/apidb/apidb.hpp: No such file or directory
That hpp file isn't installed by openstreetmap-cgimap make install

--------------------
cgimap itself compiled fine on this system, so I'm confused as to what library might be missing, or whether this is a bogus error being shown for some other reason.
Compiling fails, but I'm not sure if the output is misleading, since it certainly doesn't match the details in mkmf.log

When writing gems it's best to avoid using Gemfile.lock and instead put dependencies into a .gemspec file. Further reading at http://yehudakatz.com/2010/12/16/clarifying-the-roles-of-the-gemspec-and-gemfile/
