I started the little game on this Ubuntu 16.04 where I have no admin rights

$ readelf -V `which dvisvgm` | grep 3.4.15
  010:   2 (GLIBC_2.2.5)   5 (GLIBCXX_3.4.15)    6 (GLIBC_2.3)     4 (GLIBCXX_3.4)
  08c:   4 (GLIBCXX_3.4)   2 (GLIBC_2.2.5)   5 (GLIBCXX_3.4.15)    8 (CXXABI_1.3) 
  0x0090:   Name: GLIBCXX_3.4.15  Flags: none  Version: 5

$ readelf -V `which dvisvgm` | grep 2.14
  0f8:   4 (GLIBCXX_3.4)   4 (GLIBCXX_3.4)   4 (GLIBCXX_3.4)   d (GLIBC_2.14) 
  0x00e0:   Name: GLIBC_2.14  Flags: none  Version: 13

$ readelf -s `which dvisvgm` | grep 2.14
   251: 0000000000000000     0 FUNC    GLOBAL DEFAULT  UND memcpy at GLIBC_2.14 (13)

$ readelf -s `which dvisvgm` | grep 3.4.15
    17: 0000000000000000     0 FUNC    GLOBAL DEFAULT  UND _ZNSt8__detail15_List_nod at GLIBCXX_3.4.15 (5)
   142: 0000000000000000     0 FUNC    GLOBAL DEFAULT  UND _ZNSt8__detail15_List_nod at GLIBCXX_3.4.15 (5)

This seems to indicate that to palliate 
$ dvisvgm --version
dvisvgm: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by dvisvgm)
dvisvgm: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by dvisvgm)


I would have to hack only the two memcpy and (?) _ZNSt8__detail15_List_nod functions 

If I had not two overdue over important deadlines I could try it out at least.

Don't know if LD_PRELOAD would be honored though. (I was even surprised readelf
was available; earlier when I connected over ssh I basically had nothing to
my disposable, I only did it to access a "push new files to work homepage" command)
