GHC and GHCi use different syntax for dynamic libraries

Loading libcharm.dylib into GHCi works as follows:

$ ghci -lcharm
GHCi, version 7.0.2: http://www.haskell.org/ghc/  :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Loading object (dynamic) charm ... done
final link ... done
Prelude>

-lcharm works for GCC, too.

$ gcc -o hellocharm.c -lcharm

But not GHC.

$ ghc --make -fforce-recomp -o hellocharm hellocharm.hs charm.hs -lcharm
[1 of 2] Compiling Charm            ( Charm.hs, Charm.o )
[2 of 2] Compiling Main             ( hellocharm.hs, hellocharm.o )
Linking hellocharm ...
ld: library not found for -lcharm
collect2: ld returned 1 exit status
make: *** [hellocharm] Error 1

Inexplicably, a different flag must be used: -dylib-install-name flag must be used instead.

$ ghc --make -fforce-recomp -o hellocharm hellocharm.hs charm.hs charm.c -I/usr/include -dylib-install-name /usr/lib/libcharm.dynlib
[1 of 2] Compiling Charm            ( charm.hs, charm.o )
[2 of 2] Compiling Main             ( hellocharm.hs, hellocharm.o )
Linking hellocharm ...

Why the weird syntax? It seems that in this regard, GHCi is actually closer to GCC syntax than GHC.
