clisp: dyld: Library not loaded: /opt/local/lib/libsigsegv.2.dylib

[jwiegley@…]

When I try to build clisp, it complains that libsigsegv is not installed. I installed that, still complained. I installed it again with +universal, it still complained.

So I installed it with +nolibsigsegv. It built successfully, but when I run it it crashes because it can't find libsigsegv!!

Does the file /opt/local/lib/libsigsegv.2.dylib exist? Is it a valid library and built for the right architectures? (What does "lipo -info /opt/local/lib/libsigsegv.2.dylib" say?)

I issued "sudo port install clisp +nolibsigsegv -f" on OSX 10.6.2 and was successfully able to invoke clisp 2.48 from the command line. I did ensure that /opt/local/lib contained no "libsigsegv" cruft, which appeared to remain after port cleans. You might try this.

Of course "sudo port clean" would not remove anything from /opt/local/lib; that is not its function. "sudo port deactivate libsigsegv" or "sudo port uninstall libsigsegv", on the other hand, should remove all parts of libsigsegv if it was MacPorts that originally installed it.

Replying to ryandesign@…:

It does not exist.

I just noticed a change in MacPorts 1.9 caused a problem for the clisp port on Snow Leopard, which I've fixed in r69483. Please see if clisp @2.48_1 fixes the problem.

Actually, that might not help; I think you're seeing #25580.
