build failed ... Couldn't find file mpc-1.0.1.tar.gz anywhere...

EasyBuild version: 3.5.1
Modules type: Tcl Environment Modules, v3.2.10
OS: CentOS 6.8

We have EasyBuild installed and configured with the required options. Commands like eb -S [software] and eb [easybuild-file] -Dr work, but the out-of-the-box WRF install referenced in the docs is failing with the following trace:

== building and installing GCC/4.7.2...
== fetching files...
== FAILED: Installation ended unsuccessfully (build directory: /home/ndusek/easybuild/build/GCC/4.7.2/dummy-dummy): build failed (first 300 chars): Couldn't find file mpc-1.0.1.tar.gz anywhere, and downloading it didn't work either... Paths attempted (in order):

I've left out the specific paths, but any clue as to what the problem is here? I figure it must be something basic I'm missing since GCC should be pretty easy to install.

The problem is that MPC has changed the download locations. This is already fixed in our develop branch, see easybuilders/easybuild-easyconfigs#5662.

To work around this, you can download the tarball manually to the location that EasyBuild would (see ‘sourcepath’ in the output of ‘eb --show-config’)

Ok, thank you. I was about to post a comment saying I worked around it by modifying the source URL in the .eb file and that seems to have worked. I will consider the above approach for future fixes as well.
