load-path weirdness for package installs

load-path weirdness for package installs

[Sivaram Neelakantan]

I've started to use the Emacs package manager for all my package
installs that go into .Emacs.d.  However every once in a while, a
package fails to load and I have to explicitly hardcode the path to
the elpa directory.

I have no idea why it happens.  Case in point

(push "c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/mic-paren-3.8" load-path)
(require 'mic-paren) ; loading
(paren-activate)     ; activating

C-h v load-path shows that the path is already there (elided the list
a bit)

("c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/all-1.0/" "c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/auctex-11.88.1/"... "c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/mic-paren-3.8/" ... "c:/gnu/elisp/org-mode/lisp/" "c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/mic-paren-3.8" ...)

This is on a win 7 Emacs build.  And the issue also appears on debian
wheezy backport of emacs24.4

Show a backtrace when it fails, then perhaps someone might have an
idea.  So far you just described a strange failure, but show no
evidence that can be used to try to figure out what might go wrong.

Btw, does "once in a while" mean that this fails with some specific
packages, or does it mean that the same package sometimes loads and
sometimes doesn't?

Warning (initialization): An error occurred while loading `c:/Users/ADMIN/AppData/Roaming/.emacs':

File error: Cannot open load file, no such file or directory, mic-paren

mic-paren is available as can be seen from the load paths(elided)

("c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/all-1.0/"
...
"c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/mic-paren-3.8/"
"c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/nlinum-1.5/"
"c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/pkg-info-0.5/"
"c:/Users/ADMIN/AppData/Roaming/.emacs.d/elpa/epl-0.7/"

...
"c:/gnu/emacs-24.4/share/emacs/24.4/lisp/calc"
"c:/gnu/emacs-24.4/share/emacs/24.4/lisp/obsolete")

With the above, I don't know why it doesn't load. the files in the
directory are 

mic-paren-autoloads.el
mic-paren-pkg.el
mic-paren-pkg.elc
mic-paren.el
mic-paren.elc

Sorry, wasn't clear.  I meant, it happens for specific packages and
not that the same packages fails sometimes and loads sometimes.

Please show the code in your .emacs that tries to load mic-paren.

Also, what does the below produce?

  M-x locate-library RET mic-parent RET
