>Description:
When building the HEAD branch of pkgsrc with pbulk in a sandbox, the build step of lang/guile22 blocks with the following state:
STAT WCHAN   COMMAND

The characteristics of the building platform are:

 I'm not sure if it's the same issue you're seeing, but for me guile
 (on NetBSD-current) something hangs. Nothing to do with build-jobs.

 The attached simple script works around it.

 (Some people also see this with cmake, that's why that is included as
 well.)

 Do we have an intuition where this issue come from? I also had misc/xdg-utils that blocked with a parked process while it successfully built in my previous pbulk. I'm afraid this is a bigger problem than lang/guile22.

 I haven't heard of xdg-utils being affected too, so I guess you have a
 different problem.

 The guile/cmake issue is tracked here:

 I didn't write the exact command down but I remember that the parked process was processing xml. I will try STOP/CONT the last time I will face this kind of blocking.

 The workaround script unblocks the build step of lang/guile.
 But it also unblocks the installation step of lang/nodejs (kill -STOP <pid>;sleep 1;kill -CONT <pid>)
