Hm, I don't know about "mlgtk", but what concerns the PCRE, you need not
install it anywhere to use it. The only thing you have to do is place
directory "{whatever}/pcre_ocaml/pcre-OCaml" on the include- and the
library path when you compile/link your project.
In case you also use my "OcamlMakefile", this should be fairly easy, e.g.
add something like:
INCDIRS = ../../pcre-OCaml
LIBDIRS = ../../pcre-OCaml
LIBS = pcre

I don't see any problem here - just "entering" into the directory of the
"third-party" distribution, "making" and including the directory with the
generated libraries should work fine.

"config.h" is generated by "configure" automatically and is actually part
of the C-library "pcre", which I always copy verbatim from its author.
Unless you also copy this "configure"-script out of its assigned directory
into your source dir, it won't do any harm to your files.

This is impossible. How do you want to guarantee that files of other people
don't get overwritten if you mix some distribution with theirs? That's what
directories are for!

I always prefix C-identifiers with very unique names so as to avoid
name-clashes. I also don't see any "main"-routine in the underlying
PCRE-library other than in example files.

I agree on this: a standard way for adding libraries, etc., would probably
boost productivity...
