   I would like to install a "module" (ie, package-private shared-object
   library to be loaded by libltdl) sans the .la file and w/ perms -x.
   Sans .la because the package has other mechanisms for keeping track
   of modules (and their dependencies); the .la is superfluous.  Perm -x
   mostly because i'm irrationally paranoid about +x.

BTW, here are some other folks looking to avoid installing the .la file
(they don't mention -x munging, however):

I see that libtool needs the .la files for `mode=uninstall', so at the
risk of further annoying the libtool maintainers, below is a shell
script for those foolhardy enough to remove the .la file, that effects a
"libtool --mode=uninstall".  It only works if you have the .la file in
the build tree.  Note that the script "sofix" mentioned in the comments
is part of ttn-do:

http://www.gnuvola.org/software/ttn-do/

and is the "rightfully denounced" program i referred to in the previous
message.  I hope these (pair of) kludges can be useful to other libtool
users, even if they are, you know, kludges.
