I'm a newbie mantainer and I'm confused about the buildbot

[Leonardo Brondani Schenkel]

Hi,

I recently started maintaining some MacPorts packages. For the first 
time today I got a message from the buildbot: apparently the neomutt 
package does not build on OS X 10.5 PPC due to '_safe_malloc' being 
undefined 
(https://build.macports.org/builders/ports-10.5_ppc_legacy-watcher/builds/632). 
My first question is regarding the procedure for failed builds: what is 
it expected that I as the maintainer should do in this case? Should I 
notify upstream and so maybe we could come up with a patch? Something else?

After that mail I got dozens of mails today from the buildbot regarding 
other unrelated packages, many just a few seconds or minutes apart. Is 
this expected or was there a glitch? I don't get why I'm getting mails 
for packages that I didn't change or maintain.

Maybe what I am asking is explained somewhere in the documentation, but 
honestly I couldn't find it. I may be looking at the wrong place.

Thanks in advance for any help,
Leonardo.
