I'm running into an problem that after building 7.5.beta1 or 7.5.beta2, 
building a branch based on 7.4.beta5 fails for two packages: cysignals-1.1.1 
and mistune-0.7.3. The only way I've found around it so far is to run make 
dist-clean && make but that takes more time than should be necessary.

Is this an error others have encountered? Is there a faster way to get past 
it? Logs attached for these two packages.

Please email sage-devel (http://groups.google.com/group/sage-devel)
explaining the problem and including the relevant part of the log file
  /Users/Masson/Downloads/GitHub/sage/logs/pkgs/cysignals-1.1.1.log
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/Users/Masson/Downloads/GitHub/sage/local/var/tmp/sage/build/cysignals-1.1.1 
and type 'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
  (cd 
'/Users/Masson/Downloads/GitHub/sage/local/var/tmp/sage/build/cysignals-1.1.1' 
&& '/Users/Masson/Downloads/GitHub/sage/sage' --sh)
When you are done debugging, you can type "exit" to leave the subshell.

Error installing package mistune-0.7.3
************************************************************************
Please email sage-devel (http://groups.google.com/group/sage-devel)
explaining the problem and including the relevant part of the log file
  /Users/Masson/Downloads/GitHub/sage/logs/pkgs/mistune-0.7.3.log
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/Users/Masson/Downloads/GitHub/sage/local/var/tmp/sage/build/mistune-0.7.3 and 
type 'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
  (cd 
'/Users/Masson/Downloads/GitHub/sage/local/var/tmp/sage/build/mistune-0.7.3' && 
'/Users/Masson/Downloads/GitHub/sage/sage' --sh)
When you are done debugging, you can type "exit" to leave the subshell.
