@kalmarek thanks, i got a report on the same issue by @sebastianpos today. I don't quite understand why Travis doesn't catch this, so besides fixing this, I'll have to make sure Travis catches it next time around.

[fingolfin]

Could either of you perhaps send me the full build.log (resp. attach it here)

[kalmarek]

actually I've just tried with GAP_INSTALL_PACKAGES=yes
https://gist.github.com/kalmarek/5e91df6f820417e506c2a6e8b9ce8650

[fingolfin]

So this regression seems to be caused by a change in Julia (in PKg.jl, I guess?) which now does a chmod a-w on all source files. It's still not clear to me why this doesn't show up on Travis.

[kalmarek]

I'll try this tomorrow, thanks!
(for tracking this while the hell broke on the email ;-)

[fingolfin]

I made a PR, if it works for you, I'll make a new release of GAP.jl ASAP

[kalmarek]

fixed by #307
