title: No Module error from minidump_stackwalk in Breakpad
body: <p>I have started working with google breakpad on Linux very recently. I have cloned it and built it successfully. I followed the steps given in: <a href="https://chromium.googlesource.com/breakpad/breakpad/+/master/docs/linux_starter_guide.md" rel="nofollow noreferrer">https://chromium.googlesource.com/breakpad/breakpad/+/master/docs/linux_starter_guide.md</a>. I have created my minidump file and symbol file successfully but when I run minidump_stalkwalk I get this:</p>
