what have I done wrong?

Where should I add the -fPIC switch?

-fPIC needs to go into dmd's configuration file.

Are you on a 32-bit system?
(For 64-bit -fPIC is the default since 2.072.2 - though DMD's 
build scripts were only updated a few releases later)

No, I have my own build script for dmd, though because I can't 
get Digger to work either.

What error do you get with Digger?
Note that you the version on Dub just has been updated today:

https://github.com/dlang-bots/dlang-bot/pull/194#issuecomment-375993106

For building everything locally, it should be as easy as:

---
git clone https://github.com/dlang/dmd
git clone https://github.com/dlang/druntime
git clone https://github.com/dlang/phobos
cd phobos && make -f posix.mak -j10
---

(dmd + druntime are built automatically from Phobos)

I advise against rolling your own built script and reporting your 
issues either here, Slack or IRC.
If we can reproduce your issue, chances are that someone else 
will run into them too ;-)

BTW there's also this setup script:

https://github.com/dlang/tools/blob/master/setup.sh

How do I build a release-inline-nobounds build with ldc? I want 
to set

- DC=ldmd2,
- ENABLE_RELEASE=1

when building dmd.

 BTW there's also this setup script:

 https://github.com/dlang/tools/blob/master/setup.sh

Thanks.

1) With LDC
------------

make -f posix.mak HOST_DMD=ldmd (or ldmd2 - depending on your 
distro)

2) Release mode params
-----------------------

It's defined here:

https://github.com/dlang/dmd/blob/master/src/posix.mak#L242

It doesn't add -noboundscheck by default.
Typically the Makefiles allow passing an initial DFLAG variable, 
but that one doesn't seem to allow it, so I just submitted a PR 
to do so (https://github.com/dlang/dmd/pull/8089).
With this PR you can do:

make -f posix.mak HOST_DMD=ldmd ENABLE_RELEASE=1 
DFLAGS="-noboundscheck"

You might want to give ENABLE_LTO a try too.
