problem with LHAPDF6

Dear experts,

I'm trying to generate events using new PDF sets, so I installed LHAPDF 6.1.5 in the MG5_aMC_v2_2_2 directory.

./configure --prefix=/.../MG5_aMC_v2_2_2/
make
make install

Next, I downloaded NNPDF30_lo_as_0130_nf_4.tar.gz in /.../MG5_aMC_v2_2_2/share/LHAPDF and copied LHAPDF to lib/PDFsets.

Then I generated events (p p > e+ e-) and changed PDF in the run_card.dat

# PDF CHOICE: this automatically fixes also alpha_s and its evol. *
#*********************************************************************
 'lhapdf' = pdlabel ! PDF set
 263400 = lhaid ! if pdlabel=lhapdf, this is the lhapdf number

But I got an error message like this.

INFO: compile directory
Command "generate_events " interrupted with error:

And here is the log file.

Since I don't know well how to install LHAPDF6 in MG5, please give me some comments.
Thanks in advance for your help.
