Syntax error for distributed loop

[kafisatz]

It is not clear to me why the following produces a syntax error.
Without ProgressMeter.@showprogress things work fine (see second line in the function me)

using Distributed 
using ProgressMeter 

function simulateSensitivity(sett,sensmatinput,i,get_metrics,tmpoutputfldr)
    return nothing 
end

function me(sensmatinput,tmpoutputfldr,get_metrics,sett,i)
    keymetrics = ProgressMeter.@showprogress 2 "Running sensitivities..." Distributed.@distributed (vcat) for i in 1:size(sensmatinput,1) #does not work
    #keymetrics =                                                         Distributed.@distributed (vcat) for i in 1:size(sensmatinput,1) #works
    #do some work
         sett = deepcopy(mainsett)
         tmpoutputfldr = mkdir(joinpath(outputfld,string(i)))
         #.......
         keym = simulateSensitivity(sett,sensmatinput,i,get_metrics,tmpoutputfldr)
    end

    return nothing 
end

@showprogress recognizes @distributed but not Distributed.@distributed
