Hi,
I'm having the same problem that you had. I have installed the libsoup2.4-dev and then it says:
checking for LIBSOUP... configure: error: Package requirements (libsoup-2.4 >= 2.28.2) were not met:
Requested 'libsoup-2.4 >= 2.28.2' but version of libsoup is 2.4.1
How did you solve it?
Best Regards,
John
