(Linking) issue with MacGPG2

I would like to inform you that the current MacGPG installer breaks other installations. As an example:

This file (which is created during installation of some ruby gems)
compiles fine with `gcc-4.2 -o conftest conftest.c -liconv`, but not
with `gcc-4.2 -o conftest conftest.c -I/usr/local/MacGPG2/include -liconv`

--- snip ------------------------------------------------------------
#include <iconv.h>

int t() { void ((*volatile p)()); p = (void ((*)()))iconv_open; return 0; }
/* int t() { iconv_open(); return 0; } */
int main(int argc, char **argv)
if (argc > 1000000) {
printf("%p", &t);

return 0;
--- snap ------------------------------------------------------------

What I make of it is that the copy of iconv.h, that comes bundled with MacGPG2
in /usr/local/MacGPG2/include somehow sets up the compiler to link with the libiconv
library in /usr/local/MacGPG2/lib, which is somehow not compatible with the one in
/usr/lib (probably compiled for 32bit?) I think it would be nice to either

a) not install any headers at all, or
b) not install the iconv headers, and instead use the ones provided by OSX, or
c) install headers in non-default locations.

This is on OSX 10.7 with the recent MacGPG2 release.

    Hi eno,

    not sure why the include folder of /usr/local/MacGPG2/include is even considered, but we'll make sure to exclude it in future releases.

    Thanks for reporting.
