Hello,

I'm trying to build OLA (Open Lighting Architecture) and I ran into some
difficulty.  Ola is often used as a service, but at this point all I'm
interested in is making an ordinary package.  The build times out after
a certain point:

    g++ -DHAVE_CONFIG_H -I.    -I./include -I./include -Wall -Wformat -W -fvisibility-inlines-hidden -pthread -Werror  -DTEST_SRC_DIR=\".\" -DTEST_BUILD_DIR=\".\" -g -O2 -pthread -MT common/messaging/common_messaging_DescriptorTester-SchemaPrinterTest.o -MD -MP -MF common/messaging/.deps/common_messaging_DescriptorTester-SchemaPrinterTest.Tpo -c -o common/messaging/common_messaging_DescriptorTester-SchemaPrinterTest.o `test -f 'common/messaging/SchemaPrinterTest.cpp' || echo './'`common/messaging/SchemaPrinterTest.cpp
    building of `/gnu/store/m0qkm9zwjaaynnn8pl0r1m6avbv0lhs0-ola-0.10.2.drv' timed out after 3600 seconds of silence
    @ build-failed /gnu/store/m0qkm9zwjaaynnn8pl0r1m6avbv0lhs0-ola-0.10.2.drv - timeout
    guix build: error: build failed: build of `/gnu/store/m0qkm9zwjaaynnn8pl0r1m6avbv0lhs0-ola-0.10.2.drv' failed

Attached is the package definition so far.
