I just checked on Ubuntu 14.04 with the Mono Xamarin packages:

locate Microsoft.Build.Tasks.v4.0
shows:
/usr/lib/mono/4.0/Microsoft.Build.Tasks.v4.0.dll
/usr/lib/mono/4.5/Microsoft.Build.Tasks.v4.0.dll
/usr/lib/mono/gac/Microsoft.Build.Tasks.v4.0
/usr/lib/mono/gac/Microsoft.Build.Tasks.v4.0/4.0.0.0__b03f5f7f11d50a3a
/usr/lib/mono/gac/Microsoft.Build.Tasks.v4.0/4.0.0.0__b03f5f7f11d50a3a/Microsoft.Build.Tasks.v4.0.dll

dpkg -S /usr/lib/mono/4.5/Microsoft.Build.Tasks.v4.0.dll
shows:
libmono-microsoft-build-tasks-v4.0-4.0-cil:
/usr/lib/mono/4.5/Microsoft.Build.Tasks.v4.0.dll

do you have that dll?
it belongs to package libmono-microsoft-build-tasks-v4.0-4.0-cil and
installs when I run apt-get install mono-devel
