Trying to compile git head on OSX 10.7.5 with ./configure --without-qt --disable-tests --disable-debug, it fails with:
checking whether the Boost::Chrono library is available... yes
checking for exit in -lboost_chrono-mt... yes
configure: error: No working boost sleep implementation found
I have boost installed with MacPorts:
> port installed | grep boost
boost [@1](/bitcoin-bitcoin/contributor/1/).54.0_0+no_single+no_static+python27 (active)
