libtool does not install libltdl.dylib

[christophe@…]

Simply doing. on 10.6.8: sudo port install imagemagick,

I get:

--->  Computing dependencies for ImageMagick

Error: The file /opt/local/lib/libltdl.dylib does not exist, though it was

Then please do what the error message says, and run "sudo port -n upgrade --force libtool"

Did that (sudo port -n upgrade --force libtool), but it still does not work. Btw, the error says libltdl, not libtool.

Following the exact error message, I do: sudo port -n upgrade --force imagemagick

And then I get (not surprisingly): Error: imagemagick is not installed

The weird thing is that when I look under /opt/local/lib, I have: libltdl.a and libltdl.la, but no libltdl.dylib.

[christophe@…]

A bit more info.

Just to try to see what is going on, I removed the two .a files (/opt/local/lib/libltdl.a and /opt/local/lib/libltdl.la).

Then I ran your proposed "sudo port -n upgrade --force libtool".

This re-installed the two .a files, but did not bring in the corresponding libltdl.dylib.

Yes. libltdl.dylib is the LibTool Dynamic Loader, which was supposed to have been provided by the libtool port, but on your system it was not. I need to see the main.log file from the libtool build in order to determine why that happened. This same problem has previously been reported in #25417 and #23684. The presence of the file /usr/bin/gfortran may be implicated. Do you have this file? If so remove it and try rebuilding libtool again. I have modified the libtool port in r80123 to prevent its installation if libltdl.dylib did not get built.

[christophe@…]

This worked! I indeed had the file /usr/bin/gfortran (which was a link to /usr/bin/gfortran-4.2). Moved it out of the way, and now libtool brings in the libltdl.dylib file (which itself is a link to libltdl.7.dylib). And Imagemagick compiles and install fine. Thanks for your help. Not sure where I got this gfortran from (another macports install, likely).

[ryandesign (Ryan Carsten Schmidt)]

MacPorts does not install things in /usr.

If you need gfortran, install a MacPorts gcc port (such as gcc46).
