Normally, yes, but I installed in the same directory as the source. :-)

Anyway, I have no idea why the above didn't work, but it works now.
I haven't changed any of the files since the last time:

address@hidden ~/guile-1.8.5 $ gcc test.c -Iinclude lib/libguile.a -lgmp -lm 
-lltdl -lcrypt
lib/libguile.a(posix.o): In function `scm_tmpnam':
posix.c:(.text+0x14b0): warning: the use of `tmpnam' is dangerous, better use 
`mkstemp'
address@hidden ~/guile-1.8.5 $ ./a.out
main: 0x804cd54, p: 804cd54
address@hidden ~/guile-1.8.5 $
