When building emacs add ons, it's necessary to install the byte
compiled (*.elc) files with -p so that when both the uncompiled
(*.el)and byte compiled files are installed emacs will read the byte
compiled sources - emacs looks at the timestamps of both the el and
elc and loads the elc if it's mtime is later than the .el. Not using
-p often results in emacs disregarding the elc file if the el source
file is installed, negating the usefulness of byte compilation.
Um, sorry, I got that backwards - the non byte compiled .el files need
to be installed with -p, sorry. But you get the point.
Firstly, I don't deny that there are (very few) special cases in which
INSTALL="install -p" might be necessary to work-around particular issues
with certain packages (IIRC, some java packages have a similar problem).
However, it's equally easy to produce examples, in which
INSTALL="install -p" has harmful effects.
That said, to me, INSTALL="install -p" is just a special case of
environment variables, similar to many other special environment
variables needed by certain packages.

[I for one would read your issue's description as an upstream bug. If
they have special demands on timestamps, they need to take care about it.]
