OS X 10.10: generating [profile] takes very long (~ 5 min)

[certik]

The actual package compilation is reasonable, but when it's time to generate the profile it takes extremely long, easily 5 min or more. I.e. executing the following lines takes a long time:

[profile] Building profile/gemoqllbe2xw, follow log with:
[profile]   tail -f /Users/certik/.hashdist/tmp/profile-gemoqllbe2xw/build.log
[profile] running ['hit', 'create-links', u'/Users/certik/.hashdist/tmp/profile-gemoqllbe2xw/job/50_in0.json']
[profile] running ['hit', 'build-postprocess', '--write-protect']
Profile build successful, link at: default

I don't know what the problem is. On linux it is very fast.
