 Anyhow, [issues with rpaths persist][persist].  Since it both hard to
 predict all installation configurations at compile time, and tools to
-change rpaths later on (i.e. `chrpath`) aren't able to increase the
-size of the rpath string on Linux ([they can on Solaris][solaris],
-because Solaris leaves a bit of padding at the end of the dynamic
-string table in the compiled [ELF][] file).  This means you will have
-trouble moving a library out of the standard library path into some
-out-of-the-way location.  However, in the more common case of
-installing a library *into* the standard library path, `chrpath` is
-the tool you need, and it solved my comedilib QA issue.
