Thanks, that was the right cue. I had previously removed the build directory a couple of times and freshly unpacked the tarball,
but it did not work. Now, instead of compiling on the login node, I tried compiling on a compute node, which finally worked.

FYI, I think the reason was the following. In addition to the error message I cited in my email, there were some non-critical error messages during the build process,
stating that some directory in /tmp already exists. I suspect that these messages were coming from the linker and that it must have been be due to these /tmp directories, from a
first compilation attempt, that the build process choked.
