Could someone point me to simple step-by-step instructions
for complete installation of GPC on Mac OSX 10.5?

I got:
GNU Pascal 3.4.5u2 installer for Mach-O Intel (Intel native and PowerPC cross compiler) (16.6 MB)
and was able to get it installed at:


[toot:~/now/delila] tds% which gpc
[toot:~/now/delila] tds% dir /usr/bin/gpc
lrwxr-xr-x  1 root  wheel  34 Jan 29 23:19 /usr/bin/gpc@ -> /Developer/Pascal/gpc3

but when I try to compile I get:

/usr/bin/ld: can't locate file for: -lcrt1.o

(along with various warnings about my program that are ok.) I get no
compiled result.  (I also installed the Mac OS X Pascal Interfaces but
that did not help.)
--unit-path=/Developer/Pascal/GPCPInterfaces -I/Developer/Pascal/GPCPInterfaces
to my control script did not help.

I have no clue as how to fix this.
