The difference is simple - choose the Soundflower input in Audacity when you want to record streaming audio and the built-in input when you want to record a physical radio or tape deck.
If there is still a problem, open Help > Audio Device Info..., drag-select the contents, Command - C to copy, then paste that in here. Is the problem still that the iPlayer is recorded too quietly? If so, does turning up the Audacity input slider in Mixer Toolbar
http://manual.audacityteam.org/o/man/mixer_toolbar.html make any difference? It may not - I have never used Soundlower.

Yes, it does. Both the Audacity output slider and the input slider will affect the achieved volume of the recording.

If the problem is that it records too quietly, put the output slider on maximum too.

Done that too - no difference: wave peaks never more that about 0.2 with full symphony orchestra at forte. Sound is audible, but low volume.

Turn up the playback volume in iPlayer to max.

I'm trying input to Audacity from Soundflower on my Mac right now, and it works perfectly. Sound coming from Firefox or iTunes.
I can see no fault in your device info.
Please describe exactly the steps you took (including setting up Soundflower in System Preferences) to record audio playing on the computer. If iPlayer is still a problem, try iTunes or a YouTube video playing in Safari.

Are you saying that when you record then play that recording back at full volume, it is quieter than the volume at which you heard the sound in iPlayer while you were recording it?

SysPrefs: input=line-in, output=Soundflower 2ch, input volume at half, output volume at full
Audacity: input=built-in output, output=Soundflower 2ch
Wave peaks about 0.2-0.3 max
Recorded output lower volume than input sound
Same with both Firefox and Safari
Seems a bit better on YouTube, but only marginal, and the stuff I want is (so far) only on BBC Radio iPlayer
